Fast Shadow Removal Using Adaptive Multi‐Scale Illumination Transfer
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, we present a new method for removing shadows from images. First, shadows are detected by interactive brushing assisted with a Gaussian Mixture Model. Secondly, the detected shadows are removed using an ... -
Four‐Dimensional Geometry Lens: A Novel Volumetric Magnification Approach
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel methodology that utilizes four-dimensional (4D) space deformation to simulate a magnification lens on versatile volume datasets and textured solid models. Compared with other magnification methods (e.g. ... -
Interactive Mesh Smoothing for Medical Applications
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Surface models derived from medical image data often exhibit artefacts, such as noise and staircases, which can be reduced by applying mesh smoothing filters. Usually, an iterative adaption of smoothing parameters to the ... -

Massively Parallel Hierarchical Scene Processing with Applications in Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel method for massively parallel hierarchical scene processing on the GPU, which is based on sequential decomposition of the given hierarchical algorithm into small functional blocks. The computation is ... -
Measuring Privacy and Utility in Privacy-Preserving Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In previous work, we proposed a technique for preserving the privacy of quasi-identifiers in sensitive data when visualized using parallel coordinates. This paper builds on that work by introducing a number of metrics that ... -
Modelling Bending Behaviour in Cloth Simulation Using Hysteresis
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Real cloth exhibits bending effects, such as residual curvatures and permanent wrinkles. These are typically explained by bending plastic deformation due to internal friction in the fibre and yarn structure. Internal ... -
Motion Synthesis for Sports Using Unobtrusive Lightweight Body‐Worn and Environment Sensing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The ability to accurately achieve performance capture of athlete motion during competitive play in near real‐time promises to revolutionize not only broadcast sports graphics visualization and commentary, but also potentially ... -
Multiple Light Source Estimation in a Single Image
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Many high‐level image processing tasks require an estimate of the positions, directions and relative intensities of the light sources that illuminated the depicted scene. In image‐based rendering, augmented reality and ... -
Non-Oriented MLS Gradient Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce a new approach for defining continuous non-oriented gradient fields from discrete inputs, a fundamental stage for a variety of computer graphics applications such as surface or curve reconstruction, and image ... -
Non‐Local Image Reconstruction for Efficient Computation of Synthetic Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Visual prototyping of materials is relevant for many computer graphics applications. A large amount of modelling flexibility can be obtained by directly rendering micro‐geometry. While this is possible in principle, it is ... -
Patch-Collaborative Spectral Point-Cloud Denoising
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a new framework for point cloud denoising by patch-collaborative spectral analysis. A collaborative generalization of each surface patch is defined, combining similar patches from the denoised surface. The ... -

SCALe-invariant Integral Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Extraction of skeletons from solid shapes has attracted quite a lot of attention, but less attention was paid so far to the reverse operation: generating smooth surfaces from skeletons and local radius information. Convolution ... -
Sketch-Based Editing Tools for Tumour Segmentation in 3D Medical Images
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In the past years sophisticated automatic segmentation algorithms for various medical image segmentation problems have been developed. However, there are always cases where automatic algorithms fail to provide an acceptable ... -
Sketch-to-Design: Context-Based Part Assembly
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Designing 3D objects from scratch is difficult, especially when the user intent is fuzzy and lacks a clear target form. We facilitate design by providing reference and inspiration from existing model contexts. We rethink ... -
Spherical Fibonacci Point Sets for Illumination Integrals
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value ... -
Visual Analysis of Multi‐Dimensional Categorical Data Sets
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a set of interactive techniques for the visual analysis of multi‐dimensional categorical data. Our approach is based on multiple correspondence analysis (MCA), which allows one to analyse relationships, patterns, ...
