• Variational Separation of Light Field Layers 

  Johannsen, Ole; Sulc, Antonin; Goldluecke, Bastian (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, ...

  Steinhausen, Heinz Christian; Brok, Dennis den; Hullin, Matthias B.; Klein, Reinhard (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 

  Haraké, Laura; Bełtkiewicz, Dorota; Lochmann, Gerrit (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 

  Bukenberger, Dennis R.; Schwarz, Katharina; Groh, Fabian; Lensch, Hendrik P. A. (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 

  Klose, Felix; Wang, Oliver; Bazin, Jean-Charles; Magnor, Marcus; Sorkine-Hornung, Alexander (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 

  Kettern, Markus; Hilsmann, Anna; Eisert, Peter (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 

  Hell, Benjamin; Magnor, Marcus (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 

  Nalbach, Oliver; Ritschel, Tobias; Seidel, Hans-Peter (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 

  Prus, Magdalena; Eisenacher, Christian; Stamminger, Marc (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 

  Sorger, Johannes; Ortner, Thomas; Piringer, Harald; Hesina, Gerd; Gröller, Eduard (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 

  Demir, Ismail; Westermann, Rüdiger (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 

  Schlegel, Steven; Goldau, Mathias; Scheuermann, Gerik (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 

  Wang, Zhongjie; Seidel, Hans-Peter; Weinkauf, Tino (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 

  Rodolà, Emanuele; Moeller, Michael; Cremers, Daniel (The Eurographics Association, 2015)
