    • 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, ...
    • A Semi-Automated Method for Subject-Specific Modeling of the Spinal Canal from Computed Tomography Images and Dynamic Radiographs 

      Haque, Md. Abedul; Marai, G. Elisabeta (The Eurographics Association, 2013)
      Shrinkage of the spinal canal may be due to congenital or degenerative conditions, and it causes many spinerelated diseases. We present a semi-automated method to computationally reconstruct spinal canal models from static ...
    • Simulation of Time-of-Flight Sensors using Global Illumination 

      Meister, Stephan; Nair, Rahul; Kondermann, Daniel (The Eurographics Association, 2013)
      Time-of-Flight (ToF) cameras use specialized sensors and modulated infrared light to simultaneously obtain depth, amplitude and intensity images. Depth images from such cameras suffer from various errors which exhibit a ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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. ...
    • 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 ...
    • Visualizing Dissections of the Heart in a Dataflow-based Shader Framework for Volume Rendering 

      Arens, Stephan; Bolte, Matthias; Domik, Gitta (The Eurographics Association, 2013)
      Dissections in anatomic heart illustrations are an effective visualization technique and support a variety of applications in exploration and communication. In this paper we implemented a set of volume deformations imitating ...
