    • Landmark-constrained 3-D Histological Imaging: A Morphology-preserving Approach 

      Gaffling, Simone; Daum, Volker; Hornegger, Joachim (The Eurographics Association, 2011)
      The inspection of histological image sequences to gain knowledge about the original three-dimensional (3-D) morphological structure is a standard method in medical research. Its main advantage is that light microscopes ...
    • Markerless Motion Capture using multiple Color-Depth Sensors 

      Berger, Kai; Ruhl, Kai; Schroeder, Yannic; Bruemmer, Christian; Scholz, Alexander; Magnor, Marcus (The Eurographics Association, 2011)
      With the advent of the Microsoft Kinect, renewed focus has been put on monocular depth-based motion capturing. However, this approach is limited in that an actor has to move facing the camera. Due to the active light nature ...
    • A Mathematical Model and Calibration Procedure for Galvanometric Laser Scanning Systems 

      Manakov, Alkhazur; Seidel, Hans-Peter; Ihrke, Ivo (The Eurographics Association, 2011)
      Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning, medical imaging, material processing, measurement devices and laser display systems. The systems of such kind ...
    • Measuring BRDFs of Immersed Materials 

      Berger, Kai; Reshetouski, Ilya; Magnor, Marcus; Ihrke, Ivo (The Eurographics Association, 2011)
      We investigate the effect of immersing real-world materials into media of different refractive indices. We show, that only some materials follow the Fresnel-governed behaviour. In reality, many materials exhibit unexpected ...
    • Meshless Hierarchical Radiosity on the GPU 

      Zollhöfer, Michael; Stamminger, Marc (The Eurographics Association, 2011)
      Meshless radiosity is a radiosity method that is based on a point-based hierarchical discretization of the scene. This better decouples the runtime complexity from the geometric complexity of the scene and allows for an ...
    • Monocular Pose Reconstruction for an Augmented Reality Clothing System 

      Rogge, Lorenz; Neumann, Thomas; Wacker, Markus; Magnor, Marcus (The Eurographics Association, 2011)
      In this paper, we present an approach for realizing an augmented reality system for try-on of apparel. The core component of our system is a quick human pose estimation algorithm based on a single camera view only. Due to ...
    • Near-Regular Texture Synthesis by Random Sampling and Gap Filling 

      Recas, Diego Lopez; Hilsmann, Anna; Eisert, Peter (The Eurographics Association, 2011)
      This paper addresses the synthesis of near-regular textures, i.e. textures that consist of a regular global structure plus subtle yet very characteristic stochastic irregularities. Such textures are difficult to synthesize ...
    • Object-aware Gradient-Domain Image Compositing 

      Eisemann, Martin; Kokemüller, Jan; Magnor, Marcus (The Eurographics Association, 2011)
      We describe an approach to suppress bleeding artifacts without altering the boundary location in gradient-domain compositing, a technique to create seamless composites. While gradient-domain compositing has become a stan- ...
    • Partial Symmetry Detection in Volume Data 

      Kerber, Jens; Wand, Michael; Krüger, Jens; Seidel, Hans-Peter (The Eurographics Association, 2011)
      In this paper, we present an algorithm for detecting partial Euclidean symmetries in volume data. Our algorithm finds subsets in voxel data that map to each other approximately under translations, rotations, and reflections. ...
    • Particle-Based Anisotropic Sampling for Two-Dimensional Tensor Field Visualization 

      Kratz, Andrea; Kettlitz, Nino; Hotz, Ingrid (The Eurographics Association, 2011)
      We present a particle-based approach to generate unstructured distributions of elliptical samples. Size and shape of the samples are determined by a local metric that is derived from a two-dimensional tensor field. In ...
    • Pose Correction by Space-Time Integration 

      Esturo, Janick Martinez; Rössl, Christian; Fröhlich, Stefan; Botsch, Mario; Theisel, Holger (The Eurographics Association, 2011)
      The deformation of a given model into different poses is an important problem in computer graphics and computer animation. In a typical workflow, a carefully designed reference surface is deformed into a couple of poses, ...
    • Probabilistic Inverse Dynamics for Blood Pattern Reconstruction 

      Cecchetto, Benjamin T.; Heidrich, Wolfgang (The Eurographics Association, 2011)
      We present a method of reconstructing the region of origin and trajectories for particles given impact directions and positions. This method works for nonlinear trajectories, such as parabolic motion or motion with drag ...
    • Real-time Rendering of Stack-based Terrains 

      Löffler, Falko; Müller, Andreas; Schumann, Heidrun (The Eurographics Association, 2011)
      Usually, terrain rendering relies on a 2D regular grid of height values, the so called height field. Height fields describe 2.5D surfaces and are not able to present complex 3D terrain features. In contrast, a 3D data ...
    • The Recognition of Ethnic Groups based on Histological Skin Properties 

      Malskies, Christoph R.; Eibenberger, Eva; Angelopoulou, Elli (The Eurographics Association, 2011)
      We present an algorithm to recognize ethnic groups based on biologically justified features, such as melanin or hemoglobin concentrations. These biophysical features are extracted from skin reflectance spectra and allow, ...
    • RITK: The Range Imaging Toolkit - A Framework for 3-D Range Image Stream Processing 

      Wasza, Jakob; Bauer, Sebastian; Haase, Sven; Schmid, Moritz; Reichert, Sebastian; Hornegger, Joachim (The Eurographics Association, 2011)
      The recent introduction of low-cost devices for real-time acquisition of dense 3-D range imaging (RI) streams has attracted a great deal of attention. However, to date, there exists no open source framework that is explicitly ...
    • SBL Mesh Filter: A Fast Separable Approximation of Bilateral Mesh Filtering 

      Vialaneix, Guillaume; Boubekeur, Tamy (The Eurographics Association, 2011)
      Bilateral mesh filtering is a simple and powerful feature-preserving filtering operator which allows to smooth or remove noise from surface meshes while preserving important features in a non-iterative way. However, to be ...
