Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ... -
Paint and Click: Unified Interactions for Image Boundaries
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Image boundaries are a fundamental component of many interactive digital photography techniques, enabling applications such as segmentation, panoramas, and seamless image composition. Interactions for image boundaries often ... -
Panoramic Video from Unstructured Camera Arrays
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We describe an algorithm for generating panoramic video from unstructured camera arrays. Artifact-free panorama stitching is impeded by parallax between input views. Common strategies such as multi-level blending or minimum ... -
Parallel, Realistic and Controllable Terrain Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The challenge in terrain synthesis for virtual environments is to provide a combination of precise user control over landscape form, with interactive response and visually realistic results. We present a system that builds ... -
Partitioned Shadow Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build ... -
PHENOM: Interest Points on Photometric Normal Maps
(The Eurographics Association, 2015)This paper introduces a novel method for extracting features and matching points on images of texture-less surfaces. Feature points are extracted from surface normal maps recovered by Photometric Stereo. Such sparse matching ... -
Photorealistic Rendering of Mixed Reality Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Photo-realistic rendering of virtual objects into real scenes is one of the most important research prob- lems in computer graphics. Methods for capture and rendering of mixed reality scenes are driven by a large number ... -
Pixel Merge Unit
(The Eurographics Association, 2015)Multi-sample anti-aliasing is a popular technique for reducing geometric aliasing (jagged edges) and is supported in all modern graphics processors. With multi-sampling anti-aliasing, visibility and depth are sampled more ... -
Position-Based Simulation Methods in Computer Graphics
(The Eurographics Association, 2015)The physically-based simulation of mechanical effects has been an important research topic in computer graphics for more than two decades. Classical methods in this field discretize Newton’s second law and determine different ... -
Privacy Protecting, Real-time Face Re-recognition
(The Eurographics Association, 2015)We present a novel system for recognizing human individuals walking past a depth camera that is compatible with privacy protecting laws. The system is developed to support the statistical analysis of movement patterns in ... -
Quadratic Encoding for Hand Pose Reconstruction from Multi-Touch Input
(The Eurographics Association, 2015)One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multi-touch devices are an interesting interface for this task, as they are widely ... -
Real-time Content Adaptive Depth Retargeting for Light Field Displays
(The Eurographics Association, 2015)Light field display systems present visual scenes using a set of directional light beams emitted from multiple light sources as if they are emitted from points in a physical scene. These displays offer better angular ... -
Real-Time Subspace Integration for Example-Based Elastic Material
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Example-based material allows simulating complex material behaviors in an art-directed way. This paper presents a method for fast subspace integration for example-based elastic material, which is suitable for real-time ... -
Recent Advances in Adaptive Sampling and Reconstruction for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Monte Carlo integration is firmly established as the basis for most practical realistic image synthesis algorithms because of its flexibility and generality. However, the visual quality of rendered images often suffers ... -
Recent Advances in Facial Appearance Capture
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Facial appearance capture is now firmly established within academic research and used extensively across various application domains, perhaps most prominently in the entertainment industry through the design of virtual ... -
Redesign of an Introductory Computer Graphics Course
(The Eurographics Association, 2015)The redesign of our historically grown Computer Graphics course was primarily triggered by the need to incorporate modern, shader-based OpenGL. This technical modification led to discussions on the relevance of course ... -
Replaceable Substructures for Efficient Part-Based Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A popular mode of shape synthesis involves mixing and matching parts from different objects to form a coherent whole. The key challenge is to efficiently synthesize shape variations that are plausible, both locally and ... -
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ... -
Robust Statistical Pixel Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Robust statistical methods are employed to reduce the noise in Monte Carlo ray tracing. Through the use of resampling, the sample mean distribution is determined for each pixel. Because this distribution is uni-modal and ... -
