Light Field Imaging through Household Optics
(The Eurographics Association, 2015)Although light fields are well-established as a tool in image-based rendering and computer vision, their capture is still at a relatively early stage. In this article, we search for imaging situations similar to uncalibrated ... -
Variational Separation of Light Field Layers
(The Eurographics Association, 2015)Images of scenes which contain reflective or transparent surfaces are composed of different layers which are observed at different depths. Analyzing such a scene requires separating the image into its individual layers, ... -
Simulation of Water Condensation based on a Thermodynamic Approach
(The Eurographics Association, 2015)We introduce a novel approach for physically based simulation of water drops on surfaces considering the thermodynamical laws like mixing temperature, specific heat capacity, water vapor, saturation, and additional material ... -
Fast Multiplexed Acquisition of High-dynamic-range Material Appearance
(The Eurographics Association, 2015)There is tremendous demand for digital representations that allow for materials to be re-lit under as wide a range of illumination scenarios as possible. It is therefore desirable to capture the entire dynamic range of a ... -
Extrapolating Large-Scale Material BTFs under Cross-Device Constraints
(The Eurographics Association, 2015)In this paper, we address the problem of acquiring bidirectional texture functions (BTFs) of large-scale material samples. Our approach fuses gonioreflectometric measurements of small samples with few constraint images ... -
Tongue S(t)imulator - A Comprehensive Parametrized Pose Model for Speech Therapy
(The Eurographics Association, 2015)Recent digital applications in speech therapy address patients to train auditive speech comprehension, reading or semantics, in a playful way. Virtual tutors consist of three-dimensional head models for assisting the patient ... -
Rotoscoping on Stereoscopic Images and Videos
(The Eurographics Association, 2015)Creating an animation based on video footage (rotoscoping) often requires significant manual work. For monoscopic videos diverse publications already feature (semi-)automatic techniques to apply non-photorealistic image ... -
Efficient GPU Based Sampling for Scene-Space Video Processing
(The Eurographics Association, 2015)We describe a method to efficiently collect and filter a large set of 2D pixel observations of unstructured 3D points, with applications to scene-space aware video processing. One of the main challenges in scene-space video ... -
Temporally Consistent Wide Baseline Facial Performance Capture via Image Warping
(The Eurographics Association, 2015)In this paper, we present a method for detailed temporally consistent facial performance capture that supports any number of arbitrarily placed video cameras. Using a suitable 3D model as reference geometry, our method ... -
A Convex Clustering-based Regularizer for Image Segmentation
(The Eurographics Association, 2015)In this paper we present a novel way of combining the process of k-means clustering with image segmentation by introducing a convex regularizer for segmentation-based optimization problems. Instead of separating the ... -
The Bounced Z-buffer for Indirect Visibility
(The Eurographics Association, 2015)Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat ... -
Level-of-Detail for Production-Scale Path Tracing
(The Eurographics Association, 2015)Path-traced global illumination (GI) becomes increasingly important in movie production. With offscreen elements considerably contributing to the path traced image, geometric complexity increases drastically, requiring ... -
A Taxonomy of Integration Techniques for Spatial and Non-Spatial Visualizations
(The Eurographics Association, 2015)Research on visual data representations is traditionally classified into methods assuming an inherent mapping from data values to spatial coordinates (scientific visualization and real-time rendering) and methods for ... -
Vector-to-Closest-Point Octree for Surface Ray-Casting
(The Eurographics Association, 2015)GPU voxel-based surface ray-casting has positioned as an interesting alternative to rasterization-based rendering approaches, because it allows using many processing units simultaneously, can effectively exploit thread ... -
Interactive GPU-based Visualization of Scalar Data with Gaussian Distributed Uncertainty
(The Eurographics Association, 2015)We present a GPU-based approach to visualize samples of normally distributed uncertain, three-dimensional scalar data. Our approach uses a mathematically sound interpolation scheme, i.e., Gaussian process regression. The ... -
Hierarchical Hashing for Pattern Search in 3D Vector Fields
(The Eurographics Association, 2015)The expressiveness of many visualization methods for 3D vector fields is often limited by occlusion, i.e., interesting flow patterns hide each other or are hidden by laminar flow. Automatic detection of patterns in 3D ... -
Point-wise Map Recovery and Refinement from Functional Correspondence
(The Eurographics Association, 2015)Since their introduction in the shape analysis community, functional maps have met with considerable success due to their ability to compactly represent dense correspondences between deformable shapes. Despite the numerous ... -
Temporal Coherence Predictor for Time Varying Volume Data Based on Perceptual Functions
(The Eurographics Association, 2015)This paper introduces an empirical, perceptually-based method which exploits the temporal coherence in consecutive frames to reduce the CPU-GPU traffic size during real-time visualization of time-varying volume data. In ... -
Simple, Robust, Constant-Time Bounds on Surface Geodesic Distances using Point Landmarks
(The Eurographics Association, 2015)In this paper we exploit redundant information in geodesic distance fields for a quick approximation of all-pair distances. Starting with geodesic distance fields of equally distributed landmarks we analyze the lower and ... -
Data Driven 3D Face Tracking Based on a Facial Deformation Model
(The Eurographics Association, 2015)We introduce a new markerless 3D face tracking approach for 2D video streams captured by a single consumer grade camera. Our approach is based on tracking 2D features in the video and matching them with the projection of ...
