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 ... -
Assessment of Time-of-Flight Cameras for Short Camera-Object Distances
(The Eurographics Association, 2011)In this paper we have compared Time-of-Flight cameras of different vendors at object-camera distances of 500 mm, 1500 mm and 2500 mm. The aim was to find the highest possible precision at the distance of 500 mm, to estimate ... -
The Recognition of Ethnic Groups based on Histological Skin Properties
(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, ... -
Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ... -
A View-Dependent and Inter-Frame Coherent Visualization of Integral Lines using Screen Contribution
(The Eurographics Association, 2011)In vector field visualization, integral lines like stream, path, or streak lines are often used to examine the behavior of steady and unsteady flows. In 3D, however, visualizing integral lines is problematic since the ... -
A Clustering-based Visualization Technique to Emphasize Meaningful Regions of Vector Fields
(The Eurographics Association, 2011)This paper proposes a vector field visualization approach that extracts and visualizes grouped regions of static 3D vector fields of similar curvature behavior. These regions are argued to ease the recognition of regions ... -
Seamless Integration of Multimodal Shader Compositing into a Flexible Ray Casting Pipeline
(The Eurographics Association, 2011)In the last three years a number of multi-volume GPU ray casting systems have been presented. Some of them are very powerful and provide a wide variety of features. However, these approaches are either only capable of ... -
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 ... -
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 ... -
Extracting Flow Structures Using Sparse Particles
(The Eurographics Association, 2011)In recent years, Lagrangian Coherent Structures (LCS) have been characterized using the Finite-Time Lyapunov Exponent, following the advection of a dense set of particles into a corresponding flow field. The large amount ... -
RITK: The Range Imaging Toolkit - A Framework for 3-D Range Image Stream Processing
(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 ... -
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 ... -
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 ... -
Direct Visualization of Particle-Partition of Unity Data
(The Eurographics Association, 2011)Direct visualization of higher-order data provides manifold advantages over the traditional approach, which is based on resampling and subsequent visualization by interpolation-based techniques. Most important, it avoids ... -
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 ... -
Effective Back-Patch Culling for Hardware Tessellation
(The Eurographics Association, 2011)When rendering objects with hardware tessellation, back-facing patches should be culled as early as possible to avoid unnecessary surface evaluations, and setup costs for the tessellator and rasterizer. For dynamic objects ... -
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 ... -
Depth Driven Photometric and Geometric Image Registration for Real-Time Stereo Systems
(The Eurographics Association, 2011)This paper presents a novel depth driven approach for a highly accurate joint photometric and geometric image alignment. Thereby, the registration problem is expressed in terms of a consistent, elegant and efficient energy ... -
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 ... -
SBL Mesh Filter: A Fast Separable Approximation of Bilateral Mesh Filtering
(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 ...
