    • Audio Resynthesis on the Dancefloor: A Music Structural Approach 

      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 ...

      Large-scale longitudinal epidemiological studies, such as the Study of Health in Pomerania (SHIP), investigate thousands of individuals with common characteristics or experiences (a cohort) including a multitude of ...
    • A Thin Shell Approach to the Registration of Implicit Surfaces 

      Iglesias, Jose A.; Berkels, Benjamin; Rumpf, Martin; Scherzer, Otmar (The Eurographics Association, 2013)
      Frequently, one aims at the co-registration of geometries described implicitly by images as level sets. This paper proposes a novel shape sensitive approach for the matching of such implicit surfaces. Motivated by physical ...

      Lawonn, Kai; Gasteiger, Rocco; Preim, Bernhard (The Eurographics Association, 2013)
      The investigation of hemodynamic information for the assessment of cardiovascular diseases (CVD) has increased in recent years. Improved flow measuring modalities and computational fluid dynamics (CFD) simulations are ...

      Machado, Gustavo M.; Sadlo, Filip; Ertl, Thomas (The Eurographics Association, 2013)
      We present local extraction of bifurcation lines together with extraction of their manifolds, a topological feature that has not yet been sufficiently recognized in scientific visualization. The bifurcation lines are ...
    • 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 ...
    • Progressive Visibility Caching for Fast Indirect Illumination 

      Ulbrich, Justus; Novák, Jan; Rehfeld, Hauke; Dachsbacher, Carsten (The Eurographics Association, 2013)
      Rendering realistic images requires exploring the vast space of all possible paths that light can take between emitters and receivers. Thanks to the advances in rendering we can tackle this problem using different algorithms; ...
    • A Tracking Approach for the Skeletonization of Tubular Parts of 3D Shapes 

      Garro, Valeria; Giachetti, Andrea (The Eurographics Association, 2013)
      In this paper we propose a new simple and efficient method to characterize shapes by segmenting their elongated parts and characterizing them with their centerlines. We call it Tubular Section Tracking, because it consists ...
    • Optimising Aperture Shapes for Depth Estimation 

      Sellent, Anita; Favaro, Paolo (The Eurographics Association, 2013)
      The finite depth of field of a real camera can be used to estimate the depth structure of a scene. While the distance of an object from the plane in focus determines the defocus blur size, the shape of the aperture determines ...
    • 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 ...
    • Towards Multi-Kernel Ray Tracing for GPUs 

      Schiffer, Thomas; Fellner, Dieter W. (The Eurographics Association, 2013)
      Ray tracing is a widely used algorithm to compute images with high visual quality. Mapping ray tracing computations to massively parallel hardware architectures in an efficient manner is a difficult task. Based on an ...
    • 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 ...
    • Sampled and Analytic Rasterization 

      Auzinger, Thomas; Wimmer, Michael (The Eurographics Association, 2013)
      In this poster we present an overview of exact anti-aliasing (AA) methods in rasterization. In contrast to the common supersampling approaches for visibility AA (e.g. MSAA) or both visibility and shading AA (e.g. SSAA, ...
