    • 3D Shape Cropping 

      Franco, Jean-Sebastien; Petit, Benjamin; Boyer, Edmond (The Eurographics Association, 2013)
      We introduce shape cropping as the segmentation of a bounding geometry of an object as observed by sensors with different modalities. Segmenting a bounding volume is a preliminary step in many multi-view vision applications ...

      Tauscher, Jan-Philipp; Wenger, Stephan; Magnor, Marcus (The Eurographics Association, 2013)
      We propose a method for synthesizing a novel soundtrack from an existing musical piece while preserving its structure and continuity from a music theoretical point of view. Existing approaches analyze a musical piece for ...
    • Closed-Form Hierarchical Finite Element Models for Part-Based Object Detection 

      Rak, Marko; Engel, Karin; Tönnies, Klaus D. (The Eurographics Association, 2013)
      In this work we address part-based object detection under variability of part shapes and spatial relations. Our approach bases on the hierarchical finite element modeling concept of Engel and Tönnies [ET09a, ET09b]. They ...
    • Cloth-Fluid Contact 

      Huber, Markus; Eberhardt, Bernhard; Weiskopf, Daniel (The Eurographics Association, 2013)
      We present a robust and efficient method for the two-way coupling between particle-based fluid simulations and infinitesimally thin solids represented by triangular meshes. Our approach is based on a hybrid method that ...
    • Datasets and Benchmarks for Densely Sampled 4D Light Fields 

      Wanner, Sven; Meister, Stephan; Goldluecke, Bastian (The Eurographics Association, 2013)
      We present a new benchmark database to compare and evaluate existing and upcoming algorithms which are tailored to light field processing. The data is characterised by a dense sampling of the light fields, which best fits ...
    • Dynamic Time Warping Based 3D Contours 

      Croci, Simone; Smolic, Aljoscha; Wang, Oliver (The Eurographics Association, 2013)
      In this work, we present a method for computing 3D contours from the silhouettes of objects in multiple views. Our approach unwraps contours into 1D signals and computes an efficient, globally optimal alignment using a ...
    • Epipolar Plane Image Refocusing for Improved Depth Estimation and Occlusion Handling 

      Diebold, Maximilian; Goldluecke, Bastian (The Eurographics Association, 2013)
      In contrast to traditional imaging, the higher dimensionality of a light field offers directional information about the captured intensity. This information can be leveraged to estimate the disparity of 3D points in the ...
    • Evaluating the Perceptual Impact of Rendering Techniques on Thematic Color Mappings in 3D Virtual Environments 

      Engel, Juri; Semmo, Amir; Trapp, Matthias; Döllner, Jürgen (The Eurographics Association, 2013)
      Using colors for thematic mapping is a fundamental approach in visualization, and has become essential for 3D virtual environments to effectively communicate multidimensional, thematic information. Preserving depth cues ...
    • Expressive Spectral Error Visualization for Enhanced Spectral Unmixing 

      Labitzke, Björn; Urrigshardt, Frank; Kolb, Andreas (The Eurographics Association, 2013)
      A major issue in multispectral data analysis stems from the concept of spectral mixture analysis, i.e. the fact that a pixel does not cover only one material but corresponds to a mixture of materials. Even though many ...
    • Fine-Scale Editing of Continuous Volumes using Adaptive Surfaces 

      Ruhl, Kai; Wenger, Stephan; Franke, Dennis; Saretzki, Julius; Magnor, Marcus (The Eurographics Association, 2013)
      Many fields of science such as astronomy and astrophysics require the visualization and editing of smooth, continuous volume data. However, current high-level approaches to volume editing concentrate on segmentable volume ...
    • Geometric Point Light Source Calibration 

      Ackermann, Jens; Fuhrmann, Simon; Goesele, Michael (The Eurographics Association, 2013)
      We present a light position calibration technique based on a general arrangement of at least two reflective spheres in a single image. Contrary to other techniques we do not directly intersect rays for triangulation but ...
    • Illustrative Rendering of Particle Systems 

      Chandler, Jennifer; Obermaier, Harald; Joy, Kenneth I. (The Eurographics Association, 2013)
      Sets of particles are a frequently used tool for the exploration of time-varying flow fields due to their ease of use and conceptual simplicity. Understanding temporal changes in such particle systems can be difficult with ...
    • Image Based Rendering from Perspective and Orthographic Images for Autostereoscopic Multi-View Displays 

      Jung, Daniel; Koch, Reinhard (The Eurographics Association, 2013)
      Current autostereoscopic (AS) multi-view displays for video that are targeted at the market allow typically up to 60 frames per second and offer between 20 and 60 different views per pixel. Future full parallax AS displays ...
    • Integrated Multi-aspect Visualization of 3D Fluid Flows 

      Brambilla, Andrea; Andreassen, Øyvind; Hauser, Helwig (The Eurographics Association, 2013)
      The motion of a fluid is affected by several intertwined flow aspects. Analyzing one aspect at a time can only yield partial information about the flow behavior. More details can be revealed by studying their interactions. ...
