    • Kinematic ICP for Articulated Template Fitting 

      Fechteler, Philipp; Hilsmann, Anna; Eisert, Peter (The Eurographics Association, 2012)
      In this paper, we present an efficient optimization method to adapt an articulated 3D template model to a full or partial 3D mesh. The well-known ICP algorithm is enhanced to fit a generic template to a target mesh. Each ...
    • Markov Chain Driven Multi-Dimensional Visual Pattern Analysis with Parallel Coordinates 

      Geng, Zhao; Walker, James; Laramee, Robert S. (The Eurographics Association, 2012)
      Parallel coordinates is a widely used visualization technique for presenting, analyzing and exploring multidimensional data. However, like many other visualizations, it can suffer from an overplotting problem when rendering ...
    • A Mixed Shape Space for Fast Interpolation of Articulated Shapes 

      Marras, Stefano; Cashman, Thomas J.; Hormann, Kai (The Eurographics Association, 2012)
      Interpolation between compatible triangle meshes that represent different poses of some object is a fundamental operation in geometry processing. A common approach is to consider the static input shapes as points in a ...
    • Optimized Canonical Coordinate Frames for 3D Object Normalization 

      Martinek, Michael; Grosso, Roberto; Greiner, Günther (The Eurographics Association, 2012)
      In this paper, we describe a method to optimize an orthogonal system of axes for 3D objects in order to perform normalization with respect to orientation and scale. An energy function evaluates the quality of a system by ...
    • Registration of Temporal Ultrasonic Image Sequences Using Markov Random Fields 

      Schäfer, Sebastian; Toennies, Klaus (The Eurographics Association, 2012)
      Ultrasound perfusion imaging is a rapid and inexpensive technique which enables observation of a dynamic process with high temporal resolution. The image acquisition is disturbed by various motion influences due to the ...
    • Resolving Twisted Surfaces within an Iterative Refinement Surface Reconstruction Approach 

      Annuth, Hendrik; Bohn, Christian-A. (The Eurographics Association, 2012)
      We present a method which resolves twisted surface regions within a surface reconstruction approach that uses local refinement operations to iteratively fit a surface into an unorganized point cloud. We show that this local ...
    • Screen Space Spherical Harmonic Occlusion 

      Herholz, Sebastian; Schairer, Timo; Schilling, Andreas; Straßer, Wolfgang (The Eurographics Association, 2012)
      In this paper we present a new algorithm for real-time directional occlusion sampling. We combine the real-time capabilities of Screen Space Ambient Occlusion (SSAO) with the Spherical Harmonics (SH) representation of local ...
    • Segmentation of Vertebral Bodies in MR Images 

      Zukic, Dzenan; Vlasák, Ales; Dukatz, Thomas; Egger, Jan; Horínek, Daniel; Nimsky, Christopher; Kolb, Andreas (The Eurographics Association, 2012)
      Segmentation of vertebral bodies is useful for diagnosis of certain spine pathologies, such as scoliosis, spondylolisthesis and vertebral fractures. In this paper, we present a fast and semi-automatic approach for spine ...
    • Single-Pass Rendering of Day and Night Sky Phenomena 

      Müller, Daniel; Engel, Juri; Döllner, Jürgen (The Eurographics Association, 2012)
      This paper presents astronomical based rendering of skies as seen from low altitudes on earth, in respect to location, date, and time. The technique allows to compose an atmosphere with sun, multiple cloud layers, moon, ...
    • Spectral Analysis of Higher-Order and BFECC Texture Advection 

      Netzel, Rudolf; Ament, Marco; Burch, Michael; Weiskopf, Daniel (The Eurographics Association, 2012)
      We present a spectral analysis of higher-order texture advection in combination with Back and Forth Error Compensation and Correction (BFECC). Semi-Lagrangian texture advection techniques exhibit high numerical diffusion, ...
    • Visualization and Exploration of Shape Variance for the Analysis of Cohort Study Data 

      Klemm, Paul; Oeltze, Steffen; Hegenscheid, Katrin; Völzke, Henry; Toennies, Klaus; Preim, Bernhard (The Eurographics Association, 2012)
      In epidemiological studies, a group of people with common characteristics or experiences (a cohort) is studied including an analysis of socio-demographic as well as biological factors and correlations indicating per subject ...
    • Visualization of Scene Structure Uncertainty in a Multi-View Reconstruction Pipeline 

      Recker, Shawn; Hess-Flores, Mauricio; Duchaineau, Mark A.; Joy, Kenneth I. (The Eurographics Association, 2012)
      This paper presents a novel, interactive visualization tool that allows for the analysis of scene structure uncer- tainty and its sensitivity to parameters in different multi-view scene reconstruction stages. Given a set ...
    • Visualizing Dynamic Call Graphs 

      Burch, Michael; Müller, Christoph; Reina, Guido; Schmauder, Hansjoerg; Greis, Miriam; Weiskopf, Daniel (The Eurographics Association, 2012)
      Visualizing time-varying call graphs is challenging due to vast amounts of data at many dimensions to be displayed: Hierarchically organized vertices with attributes, directed or undirected edges with weights, and time. ...
    • Visualizing Solar Dynamics Data 

      Machado, Gustavo M.; Sadlo, Filip; Müller, Thomas; Müller, Daniel; Ertl, Thomas (The Eurographics Association, 2012)
      Solar dynamics data, particularly those from the Solar Dynamics Observatory, are now available in a sheer volume that is hard to investigate with traditional visualization tools, which mainly display 2D images. While the ...
