    • 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; ...
    • Transfusive Weights for Content-Aware Image Manipulation 

      Yücer, Kaan; Sorkine-Hornung, Alexander; Sorkine-Hornung, Olga (The Eurographics Association, 2013)
      Many image editing operations, such as colorization, matting or deformation, can be performed by propagating user-defined sparse constraints (e.g. scribbles) to the rest of the image using content-aware weight functions. ...
    • 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 ...
    • 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 ...
    • Interactive Direct Volume Rendering with Many-light Methods and Transmittance Caching 

      Weber, Christoph; Kaplanyan, Anton S.; Stamminger, Marc; Dachsbacher, Carsten (The Eurographics Association, 2013)
      In this paper we present an interactive global illumination method for Direct Volume Rendering (DVR) based on the many-light approach, a class of global illumination methods which gained much interest recently. We extend ...
    • 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 ...
    • Level of Detail for Real-Time Volumetric Terrain Rendering 

      Scholz, Manuel; Bender, Jan; Dachsbacher, Carsten (The Eurographics Association, 2013)
      Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
    • Visualization and Analysis of Lumbar Spine Canal Variability in Cohort Study Data 

      Klemm, Paul; Lawonn, Kai; Rak, Marko; Preim, Bernhard; Toennies, Klaus; Hegenscheid, Katrin; Völzke, Henry; Oeltze, Steffen (The Eurographics Association, 2013)
      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 ...
    • 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 ...
    • 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, ...
    • Adaptive Surface Visualization of Vessels with Embedded Blood Flow Based on the Suggestive Contour Measure 

      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 ...
    • 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 ...
    • A New Framework for Fitting Shape Models to Range Scans: Local Statistical Shape Priors Without Correspondences 

      Last, Carsten; Winkelbach, Simon; Wahl, Friedrich M. (The Eurographics Association, 2013)
      Statistical shape models provide an important means in many applications in computer vision and computer graphics. However, the major problems are that the majority of these shape models require dense pointcorrespondences ...
