    QEM-Filtering: A New Technique for Feature-Sensitive Terrain Mesh Simplification
    (The Eurographics Association, 2010) Löffler, Falko; Schumann, Heidrun; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Terrain simplification generates multi-resolution models, from which - traditionally - irregular or semi-regular triangulations are extracted to render a terrain at a suitable level of detail. Recent terrain simplification techniques, in contrast, rely on GPU-friendly regular grids and generate multiple resolutions by applying the filtering and sub-sampling paradigm. However, due to the smoothing and uniform sampling, these techniques sparsely approximate the terrain surface. Consequently, in order to guarantee a certain error threshold, considerably more triangles need to be rendered. In this paper, we present a novel feature-sensitive simplification technique. Our approach follows the aforementioned paradigm. The key idea is to maintain the regularity while recomputing the vertex positions by taking a specific error metric into account, namely the quadric error metric (QEM). Compared to previous approaches, we apply the paradigm to the grid of vertex-associated quadrics. From these we extract vertices of the new resolution by relying on quadric error minimization. We, thus, maintain the regular grid structure while preserving terrain features. Compared to methods, which are solely based on vertex-filtering and sub-sampling, our approach reduces the approximation error. As a consequence, we require fewer triangles, which improves the rendering performance.

    Direct Resampling for Isotropic Surface Remeshing
    (The Eurographics Association, 2010) Fuhrmann, Simon; Ackermann, Jens; Kalbe, Thomas; Goesele, Michael; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present a feature-sensitive remeshing algorithm for relaxation-based methods. The first stage of the algorithm creates a new mesh from scratch by resampling the reference mesh with an exact vertex budget with either uniform or non-uniform vertex distribution according to a density function. The newly introduced samples on the mesh surface are triangulated directly in 3D by constructing a mutual tessellation. The second stage of the algorithm optimizes the positions of the mesh vertices by building a weighted centroidal Voronoi tessellation to obtain a precise isotropic placement of the samples. We achieve isotropy by employing Lloyd's relaxation method, but other relaxation schemes are applicable. The proposed algorithm handles diverse meshes of arbitrary genus and guarantees that the remeshed model has the same topology as the input mesh. The density function can be defined by the user or derived automatically from the estimated curvature at the mesh vertices. A subset of the mesh edges may be tagged as sharp features to preserve the characteristic appearance of technical models. The new method can be applied to large meshes and produces results faster than previously achievable.

    Graphical Interface Models for Procedural Mesh Growing
    (The Eurographics Association, 2010) Menz, Stefan; Dammertz, Holger; Hanika, Johannes; Weber, Michael; Lensch, Hendrik P. A.; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Procedural modeling allows to create highly complex 3D scenes from a small set of construction rules, which has several advantages over storing the full data of an object. The most important ones are a very small memory footprint and the ability to generate infinite variations of one prototype object by using the same set of rules. However, the problem that procedural modeling imposes on the user is to define a reasonable set of rules to generate a specific object. To simplify this task, we present new interaction metaphors for a graphical user interface and a minimal set of geometric operations that allow the user to efficiently create such rules and the respective models. These metaphors are then implemented in a prototype system and are evaluated by user tests with regard to usability and user performance. The results show that the system enables even inexperienced users to create complex 3D objects via procedural modeling using the presented approach.

    Parallel View-Dependent Out-of-Core Progressive Meshes
    (The Eurographics Association, 2010) Derzapf, Evgenij; Menzel, Nicolas; Guthe, Michael; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    The complexity of polygonal models is growing faster than the ability of graphics hardware to render them in real-time. If a scene contains many models and textures, it is often also not possible to store the entire geometry in the graphics memory. A common way to deal with such models is to use multiple levels of detail (LODs), which represent a model at different complexity levels. With view-dependent progressive meshes it is possible to render complex models in real time, but the whole progressive model must fit into graphics memory. To solve this problem out-of-core algorithms have to be used to load mesh data from external data devices. Hierarchical level of detail (HLOD) algorithms are a common solution for this problem, but they have numerous disadvantages. In this paper, we combine the advantages of view-dependent progressive meshes and HLODs by proposing a new algorithm for real-time view-dependent rendering of huge models. Using a spatial hierarchy we extend parallel view-dependent progressive meshes to support out-of-core rendering. In addition we present a compact data structure for progressive meshes, optimized for parallel GPU-processing and out-of-core memory management.

    Real-time Full-body Visual Traits Recognition from Image Sequences
    (The Eurographics Association, 2010) Jung, Christoph; Tausch, Reimar; Wojek, Christian; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    The automatic recognition of human visual traits from images is a challenging computer vision task. Visual traits describe for example gender and age, or other properties of a person that can be derived from visual appearance. Gathering anonymous knowledge about people from visual cues bears potential for many interesting applications, as for example in the area of human machine interfacing, targeted advertisement or video surveillance. Most related work investigates visual traits recognition from facial features of a person, with good recognition performance. Few systems have recently applied recognition on low resolution full-body images, which shows lower performance than the facial regions but already can deliver classification results even if no face is visible. Obviously full-body classification is more challenging, mainly due to large variations in body pose, clothing and occlusion. In our study we present an approach to human visual traits recognition, based on Histogram of oriented Gradients (HoG), colour features and Support Vector Machines (SVM). In this experimental study we focus on gender classification. Motivated by our application of real-time adaptive advertisement on public situated displays, and unlike previous works, we perform a thorough evaluation on much more comprehensive datasets that include hard cases like side- and back views. The extended annotations used in our evaluation will be published. We further show that a hierarchical classification scheme to disambiguate a person's directional orientation and additional colour features can increase recognition rates. Finally, we demonstrate that temporal integration of per-frame classification scores significantly improves the overall classification performance for tracked individuals and clearly outperforms current state-of-the-art accuracy for single images.

    Pixel-Based Hyperparameter Selection for Feature-Based Image Registration
    (The Eurographics Association, 2010) Brunet, Florent; Bartoli, Adrien; Navab, Nassir; Malgouyres, Rémy; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    This paper deals with parametric image registration from point correspondences in deformable environments. In this problem, it is essential to determine correct values for hyperparameters such as the number of control points of the warp, a smoothing parameter weighting a term in the cost function, or an M-estimator threshold. This is usually carried out either manually by a trial-and-error procedure or automatically by optimizing a criterion such as the Cross-Validation score. In this paper, we propose a new criterion that makes use of all the available image photometric information. We use the point correspondences as a training set to determine the warp parameters and the photometric information as a test set to tune the hyperparameters. Our approach is fully robust in the sense that it copes with both erroneous point correspondences and outliers in the images caused by, for instance, occlusions or specularities.

    CALTag: High Precision Fiducial Markers for Camera Calibration
    (The Eurographics Association, 2010) Atcheson, Bradley; Heide, Felix; Heidrich, Wolfgang; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present a self-identifying marker pattern for camera calibration, together with the associated detection algorithm. The pattern is designed to support high-precision, fully-automatic localization of calibration points, as well as identification of individual markers in the presence of significant occlusions, uneven illumination, and observations under extremely acute angles. The detection algorithm is efficient and free of parameters. After calibration we obtain reprojection errors significantly lower than with state-of-the art self-identifying reference patterns.

    Analysis of Structural Dependencies for the Automatic Visual Inspection of Wire Ropes
    (The Eurographics Association, 2010) Haase, Daniel; Wacker, Esther-Sabrina; Schukat-Talamazzini, Ernst Günter; Denzler, Joachim; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Automatic visual inspection is an arising field of research. Especially in security relevant applications, an automation of the inspection process would be a great benefit. For wire ropes, a first step is the acquisition of the curved surface with several cameras located all around the rope. Because most of the visible defects in such a rope are very inconspicuous, an automatic defect detection is a very challenging problem. As in general there is a lack of defective training data, most of the presented ideas for automatic rope inspection are embedded in a one-class classification framework. However, none of these methods makes use of the context information which results from the fact that all camera views image the same rope. In contrast to an individual analysis of each camera view, this work proposes the simultaneous analysis of all available camera views with the help of a vector autoregressive model. Moreover, various dependency analysis methods are used to give consideration to the regular rope structure and to deal with the high dimensionality of the problem. These dependencies are then used as constraints for the vector autoregressive model, which results in a sparse but powerful detection system. The proposed method is evaluated by using real wire rope data and the conducted experiments show that our approach clearly outperforms all previously presented methods.

    Relighting Spherical Light Fields with Polynomial Texture Mapping
    (The Eurographics Association, 2010) Brückbauer, Lisa; Rezk-Salama, Christof; Kolb, Andreas; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present a novel image-based rendering (IBR) technique based on spherical light fields, which makes it possible to relight the captured object for arbitrary viewing positions. This approach incorporates view-dependent effects such as self-shadowing and inter-reflections. For this, we apply Polynomial Texture Maps (PTMs) to 3D objects. Once acquired, a light field representation of an object can be relit at low computation costs due to the efficiency of the PTM approach. The relighting process makes even small lighting changes visible and retains surface appearance even on a meso-scale level. Furthermore, we present a simple method to adopt specular reflections captured in the PTM to novel viewing directions.

    Global Illumination using Parallel Global Ray-Bundles
    (The Eurographics Association, 2010) Hermes, Jan; Henrich, Niklas; Grosch, Thorsten; Mueller, Stefan; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    A fast computation of unbiased global illumination is still an unsolved problem, especially if multiple bounces of light and non-diffuse materials are included. The standard Monte Carlo methods are time-consuming, because many incoherent rays are shot into the scene, which is hard to parallelize. On the other hand, GPUs can make the most of their computing power if the problem can be broken down into many parallel, small tasks. Casting global, parallel ray-bundles into the scene is a way of achieving this parallelism. We exploit modern GPU features to extract all intersection points along each ray within a single rendering pass. Radiance can then be transferred between pairs of all points which allows an arbitrary number of interreflections, especially for compelling multiple glossy reflections. Beside arbitrary BRDFs, our method is independent of the number of light sources and can handle arbitrary shaped light sources in a unified framework for unbiased global illumination. Since many methods exist for fast computation of direct light using soft shadows, we demonstrate how our method can be built on top of any direct light simulation.

    Instant Texture Synthesis by Numbers
    (The Eurographics Association, 2010) Busto, Pau Panareda; Eisenacher, Christian; Lefebvre, Sylvain; Stamminger, Marc; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Appearance Space Texture Synthesis (ASTS) provides fast texture synthesis by example. Unfortunately, speed is only achieved at the cost of a long pre-processing step. This is tedious for artists and limits the input resolution. In addition, the aggressively pruned search space results in strong artifacts when synthesizing multiple textures under user guidance (Texture-By-Numbers, TBN). In this paper, we replace the k-coherence search step used by most modern synthesis algorithms with a new parallel, coherent random walk. We show that this drastically improves the synthesis quality with TBN, while maintaining the parallel nature, speed, and flexibility of the original ASTS runtime. Since it removes the expensive pre-computation of k-coherent candidates, we are able to use larger inputs, and start synthesis much faster. This is essential for artists designing high-quality exemplars.

    Proxy-Guided Texture Synthesis for Rendering Natural Scenes
    (The Eurographics Association, 2010) Bonneel, Nicolas; Panne, Michiel van de; Lefebvre, Sylvain; Drettakis, George; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Landscapes and other natural scenes are easy to photograph but difficult to model and render. We present a proxy-guided pipeline which allows for simple 3D proxy geometry to be rendered with the rich visual detail found in a suitably pre-annotated example image. This greatly simplifies the geometric modeling and texture mapping of such scenes. Our method renders at near-interactive rates and is designed by carefully adapting guidancebased texture synthesis to our goals. A guidance-map synthesis step is used to obtain silhouettes and borders that have the same rich detail as the source photo, using a Chamfer distance metric as a principled way of dealing with discrete texture labels. We adapt an efficient parallel approach to the challenging guided synthesis step we require, providing a fast and scalable solution. We provide a solution for local temporal coherence, by introducing a reprojection algorithm, which reuses earlier synthesis results when feasible, as measured by a distortion metric. Our method allows for the consistent integration of standard CG elements with the texture-synthesized elements. We demonstrate near-interactive camera motion and landscape editing on a number of examples.

    Multi-image Interpolation based on Graph-Cuts and Symmetric Optic Flow
    (The Eurographics Association, 2010) Linz, Christian; Lipski, Christian; Magnor, Marcus A.; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Multi-image interpolation in space and time has recently received considerable attention. Typically, the interpolated image is synthesized by adaptively blending several forward-warped images. Blending itself is a low-pass filtering operation: the interpolated images are prone to blurring, even if correspondences are perfect. Furthermore, ghosting artifacts appear as soon as the underlying correspondence fields are imperfect. We address both issues and propose a multi-image interpolation algorithm that avoids blending. Instead, we cast multi-image interpolation as a labeling problem and decide for each pixel in the synthesized view from which input image to sample. Combined with a symmetrical long-range optical flow formulation for correspondence field estimation, our approach yields crisp interpolated images without ghosting artifacts.

    Interactive Visualization and Tuning of SIFT Indexing
    (The Eurographics Association, 2010) Dasari, Pavan Kumar; Narayanan, P. J.; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Indexing image data for content-based image search is an important area in Computer Vision. The state of the art uses the 128-dimensional SIFT as low level descriptors. Indexing even a moderate collection involves several millions of such vectors. The search performance depends on the quality of indexing and there is often a need to interactively tune the process for better accuracy. In this paper, we propose a a visualization-based tool to tune the indexing process for images and videos. We use a feature selection approach to improve the clustering of SIFT vectors. Users can visualize the quality of clusters and interactively control the importance of individual or groups of feature dimensions easily. The results of the process can be visualized quickly and the process can be repeated. The user can use a filter or a wrapper model in our tool.We use input sampling, GPU-based processing, and visual tools to analyze correlations to provide interactivity. We present results of tuning the indexing for a few standard datasets. A few tuning iterations result in an improvement of over 4% in the final classification performance, which is significant.

    Geometry-aware Video Registration
    (The Eurographics Association, 2010) Palma, Gianpalo; Callieri, Marco; Dellepiane, Matteo; Corsini, Massimiliano; Scopigno, Roberto; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present a new method for the accurate registration of video sequences of a real object over its dense triangular mesh. The goal is to obtain an accurate video-to-geometry registration to allow the bidirectional data transfer between the 3D model and the video using the perspective projection defined by the camera model. Our solution uses two different approaches: feature-based registration by KLT video tracking, and statistic-based registration by maximizing the Mutual Information (MI) between the gradient of the frame and the gradient of the rendering of the 3D model with some illumination related properties, such as surface normals and ambient occlusion. While the first approach allows a fast registration of short sequences with simple camera movements, the MI is used to correct the drift problem that KLT tracker produces over long sequences, due to the incremental tracking and the camera motion. We demonstrate, using synthetic sequences, that the alignment error obtained with our method is smaller than the one introduced by KLT, and we show the results of some interesting and challenging real sequences of objects of different sizes, acquired under different conditions.

    Interactive Multi-View Facade Image Editing
    (The Eurographics Association, 2010) Musialski, Przemyslaw; Luksch, Christian; Schwärzler, Michael; Buchetics, Matthias; Maierhofer, Stefan; Purgathofer, Werner; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We propose a system for generating high-quality approximated façade ortho-textures based on a set of perspective source photographs taken by a consumer hand-held camera. Our approach is to sample a combined orthographic approximation over the facade-plane from the input photos. In order to avoid kinks and seams which may occur on transitions between different source images, we introduce color adjustment and gradient domain stitching by solving a Poisson equation in real-time. In order to add maximum control on the one hand and easy interaction on the other, we provide several editing interactions allowing for user-guided post-processing.

    Coherent Background Video Inpainting through Kalman Smoothing along Trajectories
    (The Eurographics Association, 2010) Bugeau, Aurélie; Gargallo, Paul; D'Hondt, Olivier; Hervieu, Alexandre; Papadakis, Nicolas; Caselles, Vicent; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Video inpainting consists in recovering the missing or corrupted parts of an image sequence so that the reconstructed sequence looks natural. For each frame, the reconstruction has to be spatially coherent with the rest of the image and temporally with respect to the reconstructions of adjacent frames. Most of existing methods only focus on inpainting foreground objects moving with a periodic motion and consider that the background is almost static. In this paper we address the problem of background inpainting and propose a method that handles dynamic background (illumination changes, moving camera, dynamic textures...). The algorithm starts by applying an image inpainting technique to each frame of the sequence and then temporally smoothes these reconstructions through Kalman smoothing along the estimated trajectories of the unknown points. The computation of the trajectories relies on the estimation of forward and backward dense optical flow fields. Several experiments and comparisons demonstrate the performance of the proposed approach.

    Tuvok, an Architecture for Large Scale Volume Rendering
    (The Eurographics Association, 2010) Fogal, Thomas; Krüger, Jens; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    In this paper we present the Tuvok architecture, a cross-platform open-source volume rendering system that delivers high quality, state of the art renderings at production level code quality. Due to its progressive rendering algorithm, Tuvok can interactively visualize arbitrarily large data sets even on low-end 32bit systems, though it can also take full advantage of high-end workstations with large amounts of memory and modern GPUs. To achieve this Tuvok uses an optimized out-of-core, bricked, level of detail data representation. From a software development perspective, Tuvok is composed of three independent components, a UI subsystem based on Qt, a rendering subsystem based on OpenGL and DirectX, and an IO subsystem. The IO subsystem not only handles the out-of-core data processing and paging but also includes support for many widely used file formats such as DICOM and ITK volumes. For rendering, Tuvok implements a wide variety of different rendering methods, ranging from 2D texture stack based approaches for low end hardware, to 3D slice based implementations and GPU based ray casters. All of these modes work with one- or multi-dimensional transfer functions, isosurface, and ClearView rendering modes. We also present ImageVis3D, a volume rendering application that uses the Tuvok subsystems. While these features may be found individually in other volume rendering packages, to our best knowledge this is the first open source system to deliver all of these capabilities at once.

    Topology-Caching for Dynamic Particle Volume Raycasting
    (The Eurographics Association, 2010) Orthmann, Jens; Keller, Maik; Kolb, Andreas; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    In this paper we present a volume rendering technique for the ad-hoc visualization of interactive particle systems. We focus on methods for an efficient spatial caching (topology caching) of particles when applying a raycasting approach. Thus, we get a fast reconstruction of the scalar field which is defined by the particles' entities. The node-cache allows for efficient caching and pre-fetching of a subset of the octree nodes. The influence-cache provides fast access to all particles which contribute to a specific node including level-of-detail particles. Finally, the introduced slab-cache allows for efficient volume rendering and gradient computation. Our algorithms are completely built and managed on the GPU and interactive frame rates for up to several 105 particles are achieved.

    (The Eurographics Association, 2010) Eichelbaum, Sebastian; Wiebel, Alexander; Hlawitschka, Mario; Anwander, Alfred; Knösche, Thomas; Scheuermann, Gerik; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Diffusion tensor images and higher-order diffusion images are the foundation for neuroscience researchers who are trying to gain insight into the connectome, the wiring scheme of the brain. Although modern imaging devices allow even more detailed anatomical measurements, these pure anatomical connections are not sufficient for understanding how the brain processes external stimuli. Anatomical connections constraint the causal influences between several areas of the brain, as they mediate causal influence between them. Therefore, neuroscientists developed models to represent the causal coherence between several pre-defined areas of the brain, which has been measured using fMRI, MEG, or EEG. The dynamic causal modeling (DCM) technique is one of these models and has been improved to use anatomical connection as informed priors to build the effective connectivity model. In this paper, we present a visualization method allowing neuroscientists to perceive both, the effective connectivity and the underlying anatomical connectivity in an intuitive way at the same time. The metaphor of moving information packages is used to show the relative intensity of information transfer inside the brain using a GPU based animation technique. We provide an interactive way to selectively view one or multiple effective connections while conceiving their anatomical connectivity. Additional anatomical context is supplied to give further orientation cues.

    Reconstructing Shape and Motion from Asynchronous Cameras
    (The Eurographics Association, 2010) Klose, Felix; Lipski, Christian; Magnor, Marcus; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present an algorithm for scene flow reconstruction from multi-view data. The main contribution is its ability to cope with asynchronously captured videos. Our holistic approach simultaneously estimates depth, orientation and 3D motion, as a result we obtain a quasi-dense surface patch representation of the dynamic scene. The reconstruction starts with the generation of a sparse set of patches from the input views which are then iteratively expanded along the object surfaces. We show that the approach performs well for scenes ranging from single objects to cluttered real world scenarios.

    Ultrasound Painting of Liver Vascular Tree
    (The Eurographics Association, 2010) Birkeland, Asmund; Viola, Ivan; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    In treatment planning and surgical interventions, physicians and surgeons need information about the spatial extent of specific features and the surrounding structures. Previous techniques for extracting features, based on magnetic resonance imaging and computed tomography scans, can be slow and cumbersome and are rarely used by doctors. In this paper we will present a novel approach to extract features from tracked 2D ultrasound, in particular hypo-echoic regions such as blood vessels. Features are extracted during live examinations, removing the need for slow and cumbersome post-scan processes and interaction is based on the natural interaction techniques used by doctors during the examination. The ultrasound probe is utilized as a 3D brush, painting features in a 3D environment. The painting occurs during a regular examination, producing little extra interaction from the doctor. We will introduce a novel approach to extract hypo-echoic regions from an ultrasound image and track the regions from frame to frame. 3D models are then generated by storing the outline of the region as a 3D point cloud. Automatically detecting branching, this technique can handle complex structures, such as liver vessel trees, and track multiple regions simultaneously. During the examination, the point cloud is triangulated in real-time, enabling the doctor to examine the results live and discard areas which are unsatisfactory. To enable modifications of the extracted 3D models, we present how the ultrasound probe can be used as a interaction tool for fast point cloud editing.

    Convex Relaxation for Grain Segmentation at Atomic Scale
    (The Eurographics Association, 2010) Boerdgen, Markus; Berkels, Benjamin; Rumpf, Martin; Cremers, Daniel; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Grains are material regions with different lattice orientation at atomic scale. They can be resolved on material surfaces with recent image acquisition technology. Simultaneously, new microscopic simulation tools allow to study mechanical models of grain structures. The robust and reliable identification and visualization of grain boundaries - in images both from simulation and from experiments - is of central importance in the field of material surface analysis. In this work, we compare a variety of variational approaches for grain boundary estimation from microscopy and simulation images. In particular, we show that grain boundary estimation can be solved by means of recently introduced convex relaxation techniques. These techniques allow to compute global solutions or solutions within a known bound of the optimum. Moreover, experimental results both on simulated and on transmission electron microscopy images confirm that the convex relaxation techniques provide significant improvements of the estimated grain boundaries over previously employed multiphase level set formulations.

    Cost-effective Feature Enhancement for Volume Datasets
    (The Eurographics Association, 2010) Díaz, Jose; Marco, Jordi; Vázquez, Pere-Pau; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Volume models often show high complexity. Local details and overall shape may sometimes be difficult to perceive. Unsharp masking techniques improve the perception of those small features by increasing the local contrast. In this paper we present a simple and fast method for feature enhancement based on 3D mipmaps. In contrast to other approaches, in addition to increasing luminance on the feature details, we also darken the valleys of the volume thus increasing local contrast and making neighboring details more visible. Our approach is fast and simple, with small memory requirements thanks to the use of 3D mipmaps. We also propose a color selection strategy, based on harmonic colors, that further enhances the salient features without abrupt or uncomfortable color changes.

    Feature Preserving Sketching of Volume Data

    In this paper, we present a novel method for extracting feature lines from volume data sets. This leads to a reduction of visual complexity and provides an abstraction of the original data to important structural features. We employ a new iteratively reweighted least-squares approach that allows us to detect sharp creases and to preserve important features such as corners or intersection of feature lines accurately. Traditional least-squares methods This is important for both visual quality as well as reliable further processing in feature detection algorithms. Our algorithm is efficient and easy to implement, and nevertheless effective and robust to noise. We show results for a number of different data sets.

    Hardware Accelerated 3D Mesh Painting
    (The Eurographics Association, 2010) Schärfig, Randolf; Hormann, Kai; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    In this paper we present a new algorithm for interactively painting onto 3D meshes that exploits recent advances of GPU technology. As the user moves a brush over the 3D mesh, its paint pattern is projected onto the 3D geometry at the current viewing angle and copied to the corresponding region in the object's texture atlas. Both operations are realized on the GPU, with the advantage that all data resides in the fast GPU memory, which in turn leads to high frame rates. A main feature of our approach is the handling of seams. Whenever the brush overlaps two or more patches, this situation is detected and the paint pattern is copied correctly to the corresponding texture charts. In this way the operation of the projection into the texture atlas is completely reduced to a single texture lookup. The performance is independent of the resolution of both the brush and the texture atlas as well as the number of mesh triangles.

    Application of Tensor Approximation to Multiscale Volume Feature Representations
    (The Eurographics Association, 2010) Suter, Susanne K.; Zollikofer, Christoph P. E.; Pajarola, Renato; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Advanced 3D microstructural analysis in natural sciences and engineering depends ever more on modern data acquisition and imaging technologies such as micro-computed or synchrotron tomography and interactive visualization. The acquired volume data sets are not only of high-resolution but in particular exhibit complex spatial structures at different levels of scale (e.g. variable spatial expression of multiscale periodic growth structures in tooth enamel). Such highly structured volume data sets represent a tough challenge to be analyzed and explored by means of interactive visualization due to the amount of raw volume data to be processed and filtered for the desired features. As an approach to address this bottleneck by multiscale feature preserving data reduction, we propose higher-order tensor approximations (TAs). We demonstrate the power of TA to represent, and highlight the structural features in volume data. We visually and quantitatively show that TA yields high data reduction and that TA preserves volume features at multiple scales.

    The Minimal Bounding Volume Hierarchy
    (The Eurographics Association, 2010) Bauszat, Pablo; Eisemann, Martin; Magnor, Marcus; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Bounding volume hierarchies (BVH) are a commonly used method for speeding up ray tracing. Even though the memory footprint of a BVH is relatively low compared to other acceleration data structures, they still can consume a large amount of memory for complex scenes and exceed the memory bounds of the host system. This can lead to a tremendous performance decrease on the order of several magnitudes. In this paper we present a novel scheme for construction and storage of BVHs that can reduce the memory consumption to less than 1% of a standard BVH. We show that our representation, which uses only 2 bits per node, is the smallest possible representation on a per node basis that does not produce empty space deadlocks. Our data structure, called the Minimal Bounding Volume Hierarchy (MVH) reduces the memory requirements in two important ways: using implicit indexing and preset surface reduction factors. Obviously, this scheme has a non-negligible computational overhead, but this overhead can be compensated to a large degree by shooting larger ray bundles instead of single rays, using a simpler intersection scheme and a two-level representation of the hierarchy. These measure enable interactive ray tracing performance without the necessity to rely on out-of-core techniques that would be inevitable for a standard BVH.

    Continuous Deformations of Implicit Surfaces
    (The Eurographics Association, 2010) Esturo, Janick Martinez; Rössl, Christian; Theisel, Holger; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We introduce an approach for the continuous deformation of implicit surfaces which considers properties of all isosurfaces of a volume data set simultaneously. This is achieved by integrating divergence-free vector fields which is carried out by an efficient backward Lagrangian integration scheme. Our deformation guarantees volume preservation inside each isosurface as well as the preservation of continuity and topology of every isosurface. For visualization and interaction, we offer a real-time mode that allows interactive working on the resolution of the underlying volumetric grid as well as a grid resolution independent mode offering exact extraction of arbitrary isosurfaces. We apply the approach to the deformation of measured volume data sets as well as to the design of complex implicit shapes with a simple pre-defined topology.

    3D Curve-Skeleton Extraction Algorithm Using a Pseudo-Normal Vector Field
    (The Eurographics Association, 2010) Pantuwong, Natapon; Sugimoto, Masanori; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    A curve skeleton is a line representation of a 3D object. It is useful in many applications, such as animation, shape matching or scientific analysis. The method described in this paper extracts a curve skeleton from the vector field which is created inside the 3D object. The topology of the vector field is analyzed to obtain the curve skeleton. In contrast with previous methods, the vector field is calculated using a pseudo-normal vector. Furthermore, by using the proposed skeleton-growing method, the vector field topology need not be computed for every voxel. Therefore, the proposed approach requires significantly less computation compared with previous vector field-based approaches, while still capturing all important parts of 3D object. The proposed method is very useful for any applications, especially real-time applications such as quick animation production and prototyping of graphical systems.

    Evaluation of Geometric Registration Methods for Using Spatial Augmented Reality in the Automotive Industry
    (The Eurographics Association, 2010) Menk, Christoffer; Jundt, Eduard; Koch, Reinhard; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Spatial augmented reality is especially interesting for the automotive industry, because in the production process of a car a lot of virtual content and also real objects are used. Therefore, the virtual content can be directly projected onto the real object to combine the advantages of the real and virtual world. One important issue for the usage of spatial augmented reality in automotive processes and applications is that the virtual content has to be projected with a very high accuracy onto the real object, because decisions are made on the basis of the projection. Therefore, we present in this article a new method for the evaluation of geometric registration techniques which align a projector to a real object. Additionally, we use this proposed method to evaluate existing geometric registration techniques. Furthermore, we present a new application where a projector is used to support the design process of a new car.

    Gerbil - A Novel Software Framework for Visualization and Analysis in the Multispectral Domain
    (The Eurographics Association, 2010) Jordan, Johannes; Angelopoulou, Elli; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Multispectral imaging has been gaining popularity and has been gradually applied to many fields besides remote sensing. Multispectral data provides unique information about material classification and reflectance analysis in general. However, due to the high dimensionality of the data, both human observers as well as computers, have difficulty interpreting this wealth of information. We present a new software package that facilitates the visualization of the relationship between spectral and topological information in a novel fashion. It puts emphasis on the spectral gradient, which is shown to provide enhanced information for many reflectance analysis tasks. It also includes a rich toolbox for evaluation of image segmentation and other algorithms in the multispectral domain. We combine the parallel coordinates visualization technique with hashing for a highly interactive visual connection between spectral distribution, spectral gradient and topology. The framework is released as open-source, has a modern cross-platform design and is well integrated into existing established computer vision software (OpenCV).

Due to its nature, this general, biologically motivated system can be parallelized efficiently on recent many-core graphics processing units (GPU). By implementing the entire pipeline on the GPU, by rigorously optimizing memory bandwidth and by minimizing branch divergence, we achieve significant speedup compared to both recent CPU as well as GPU implementations for reasonably sized feature dictionaries. We demonstrate an interactive application even on a less powerful laptop which is able to classify webcam images and to learn novel categories in real time.

    Image-Error-Based Level of Detail for Landscape Visualization
    (The Eurographics Association, 2010) Clasen, Malte; Prohaska, Steffen; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present a quasi-continuous level of detail method that is based on an image error metric to minimize the visual error. The method is designed for objects of high geometric complexity such as trees. By successive simplifications, it constructs a level of detail hierarchy of unconnected primitives (ellipsoids, lines) to approximate the input models at increasingly coarser levels. The hierarchy is constructed automatically without manual intervention. When rendering roughly 100k model instances at a low visual error compared to rendering the full resolution model, our method is two times faster than billboard clouds.

    DC-Splines: Revisiting the Trilinear Interpolation on the Body-Centered Cubic Lattice
    (The Eurographics Association, 2010) Domonkos, Balázs; Csébfalvi, Balázs; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    In this paper, we thoroughly study a trilinear interpolation scheme previously proposed for the Body-Centered Cubic (BCC) lattice. We think that, up to now, this technique has not received the attention that it deserves. By a frequency-domain analysis we show that it can isotropically suppress those aliasing spectra that contribute most to the postaliasing effect. Furthermore, we present an efficient GPU implementation, which requires only six trilinear texture fetches per sample. Overall, we demonstrate that the trilinear interpolation on the BCC lattice is competitive to the linear box-spline interpolation in terms of both efficiency and image quality. As a generalization to higher-order reconstruction, we introduce DC-splines that are constructed by convolving a Discrete filter with a Continuous filter, and easy to adapt to the Face-Centered Cubic (FCC) lattice as well.

    An Interactive, Multi-Modal Approach to Analysing High-Resolution Image Mass Spectrometry Data
    (The Eurographics Association, 2010) Smit, Ferdi A.; Liere, Robert van; Fornai, Lara; Heeren, Ron; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    The output resolution of imaging mass spectrometers is increasing rapidly due to advances in engineering and the use of tiling. Imaging-MS data is often displayed as a total-ion-count (TIC) image; however, anatomical structures are not easily identifiable from TIC images. For this purpose, additional high-resolution images that originate from different imaging modalities, such as stained histological data, are preferred. These modalities are most useful when fused; i.e., when the corresponding images are spatially aligned with respect to each other. The viewing and analysis of such data is ideally performed in real-time and at the highest possible resolution, allowing users to interactively query the combination of all fused data at the highest detail. However, proper alignment between modalities and interactively presenting large volumes of data is as of yet a challenge. We present a system for the simultaneous viewing and analysis of high-resolution data from different imaging modalities. Fusion is provided in such a way that interaction in one modality can be mapped to different modalities. For example, anatomical structures can be identified from histological data and their spatial extent mapped to a corresponding region-of-interest in the image MS data, allowing the analysis of its chemical compounds. In turn, the MS data can be analysed and filtered, for example using multi-variate analysis such as PCA, and the result mapped back to structures in other modalities. Level-of-detail, region-of-interest and asynchronous data processing algorithms ensure that the system can be operated interactively at the highest resolution.

Our hierarchical texture representation can easily be rendered in real-time, enabling zooming into specific texture regions to almost arbitrary magnification. To augment the texture map locally with high-resolution information, we describe how to automatically, seamlessly merge unregistered images of different scales. Our method is useful wherever close-up renderings of specific regions shall be provided, without the need for excessively large texture maps.

    Adaptive Image-space Stereo View Synthesis
    (The Eurographics Association, 2010) Didyk, Piotr; Ritschel, Tobias; Eisemann, Elmar; Myszkowski, Karol; Seidel, Hans-Peter; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Stereo vision is becoming increasingly popular in feature films, visualization and interactive applications such as computer games. However, computation costs are doubled when rendering an individual image for each eye. In this work, we propose to only render a single image, together with a depth buffer and use image-based techniques to generate two individual images for the left and right eye. The resulting method computes a high-quality stereo pair for roughly half the cost of the traditional methods. We achieve this result via an adaptive-grid warping that also involves information from previous frames to avoid artifacts.

    Geometric Reconstruction of the Ostium of Cerebral Aneurysms

    Polygonal 3D-reconstructions of cerebral aneurysms, combined with simulated or measured flow data provide important information for medical research, risk assessment and therapy planning. Landmarks, orientation axis, and a subdivision into functional unities, support the purposeful exploration of this complex data. The ostium, the area of inflow into the aneurysm, is the reference structure for various landmarks, axis and the initial subdivision into aneurysm's body and parent vessel.We present an approach to automatically extract important landmarks and geometrically reconstruct the ostium. Our method was successfully applied to various types of saccular aneurysms. These results were discussed with radiology experts. Our approach was considered as useful to reduce interpersonal variance in the ostium determination and forms a basis for subsequent quantification and exploration.

    Visual Analysis of Multivariate Movement Data using Interactive Difference Views
    (The Eurographics Association, 2010) Lampe, Ove Daae; Kehrer, Johannes; Hauser, Helwig; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Movement data consisting of a large number of spatio-temporal agent trajectories is challenging to visualize, especially when all trajectories are attributed with multiple variates. In this paper, we demonstrate the visual exploration of such movement data through the concept of interactive difference views. By reconfiguring the difference views in a fast and flexible way, we enable temporal trend discovery. We are able to analyze large amounts of such movement data through the use of a frequency-based visualization based on kernel density estimates (KDE), where it is also possible to quantify differences in terms of the units of the visualized data. Using the proposed techniques, we show how the user can produce quantifiable movement differences and compare different categorical attributes (such as weekdays, ship-type, or the general wind direction), or a range of a quantitative attribute (such as how two hours' traffic compares to the average). We present results from the exploration of vessel movement data from the Norwegian Coastal Administration, collected by the Automatic Identification System (AIS) coastal tracking. There are many interacting patterns in such movement data, both temporal and other more intricate, such as weather conditions, wave heights, or sunlight. In this work we study these movement patterns, answering specific questions posed by Norwegian Coastal Administration on potential shipping lane optimizations.

    Direct Image Registration without Region of Interest
    (The Eurographics Association, 2010) Brunet, Florent; Bartoli, Adrien; Navab, Nassir; Malgouyres, Rémy; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    Standard direct image registration consists in estimating the geometric warp between a source and a target images by maximizing the photometric similarity for the pixels of a Region of Interest (ROI). The ROI must be included in the real overlap between the images otherwise standard registration algorithms fail. Determining a proper ROI is a hard 'chicken-and-egg' problem since the overlap is only known after a successful registration. Almost all algorithms in the literature consider that the ROI is given. This is generally either inconvenient or unreliable. In this paper we propose a new method that registers two images without using a ROI. The key idea of our method is to consider the off-target pixels as outliers. We define the off-target pixels as those pixels of the source image mapped outside the target image by the current warp. We use the classical robust M-estimation framework to handle both the off-target pixels and the usual outliers caused, for instance, by occlusions. With our formulation, the true image overlap is defined as the set of inliers. Experiments on synthetic and real data with the homography and Free-Form Deformation show that our method outperforms standard approaches in terms of accuracy and robustness while precisely retrieving the overlap in the source and target images.

    Dynamic Focus + Context for Volume Rendering

    Interactive visualization is widely used in many applications for efficient representation of complex data. Many techniques make use of the focus+context approach in a static manner. These techniques do not fully make use of the interaction semantics. In this paper we present a dynamic focus+context approach that highlights salient features during user interaction. We explore rotation, panning, and zooming interaction semantics and propose several methods of changing visual representations, based on a suggested engagement-estimation method. We use DVR-MIP interpolation and a radial opacity-change approach, exploring rotation, panning, and zooming semantics. Our approach adds short animations during user interaction that help to explore the data efficiently and aid the user in the detection of unknown features.

    Locally Planar and Affine Deformable Surface Reconstruction from Video
    (The Eurographics Association, 2010) Collins, Toby; Bartoli, Adrien; Reinhard Koch and Andreas Kolb and Christof Rezk-Salama
    We present new solutions to tackle the problem of reconstructing a deforming surface viewed in monocular videos without a template, by exploiting the fact that many deforming surfaces are on the local scale approximately rigid and planar. The reconstruction task can then be seen, from bottom up as first multi-plane based pose estimation then dense surface reconstruction from planar samples. In practice there are major obstacles to overcome. In this paper we specifically target computing stable orientation estimates at small surface regions from interview image motion. We achieve this using local affine projection models which are stable and accurate when local perspective effects are small. Our core theoretical contributions are closed form solutions to multiview orthographic planar pose estimation in both the minimal and overdetermined cases. We use this to efficiently construct a weak deformable template; an undirected graph with nodes holding the surface's local planar structure and edges denoting physical deformation constraints. The template can then be used to recover dense 3D shape very efficiently from affine image motion via unambiguous planar pose estimation combined with surface regularisation.
