A Global Optimization Approach to High-detail Reconstruction of the Head
(The Eurographics Association, 2011)The paper presents an approach for reconstructing head-and-shoulder portraits of people from calibrated stereo images with a high level of geometric detail. In contrast to many existing systems, our reconstructions cover ... -
Implicit Filtering for Image and Shape Processing
(The Eurographics Association, 2011)The main purpose of this paper consists of demonstrating advantages of using implicit filtering schemes (noncausal IIR filters, in the signal processing language) for some basic image processing and geometric modeling ... -
Improving Stability and Compactness in Street Layout Visualizations
(The Eurographics Association, 2011)We present and evaluate improvements for Street Layout, a technique that can be used for visualizing evolving hierarchical data such as file structures or software systems. Street Layouts represent data as street networks, ... -
Instant Level-of-Detail
(The Eurographics Association, 2011)Highly detailed models are commonly used in computer games and other interactive rendering applications. In this context, static levels-of-detail are frequently used to achieve real-time frame rates. While this is a simple ... -
Interactive Exploration of Polymer-Solvent Interactions
(The Eurographics Association, 2011)The interaction of three-dimensional linked hydrophilic polymers with surrounding solvents in time-dependent data sets is of great interest for domain experts and current research in molecular dynamics. These polymers are ... -
Is it Necessary to Model the Matrix Degrading Enzymes for Simulating Tumour Growth?
(The Eurographics Association, 2011)We propose a hybrid continuum discrete model to simulate tumour growth on a microscopic scale. The lattice based spatio temporal model consists of reaction diffusion equations that describe interactions between cancer ... -
Koiter's Thin Shells on Catmull-Clark Limit Surfaces
(The Eurographics Association, 2011)We present a discretization of Koiter's model of elastic thin shells based on a finite element that employs limit surfaces of Catmull Clark's subdivision scheme. The discretization can directly be applied to control grids ... -
Landmark-constrained 3-D Histological Imaging: A Morphology-preserving Approach
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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 ...
