      Statistical shape modeling is a widely used technique for the representation and analysis of the shapes and shape variations present in a population. A statistical shape model models the distribution in a high dimensional ...
    • Effective Techniques to Visualize Filament-Surface Relationships 

      Kuß, Anja; Gensel, Maria; Meyer, Björn; Dercksen, Vincent J.; Prohaska, Steffen (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Combined visualizations of filamentous structures and surrounding volumetric objects are common in biological and medical applications. Often, the structures spatial relationships remain unclear to the viewer. In this ...
    • Estimation and Modeling of Actual Numerical Errors in Volume Rendering 

      Kronander, Joel; Unger, Jonas; Möller, Torsten; Ynnerman, Anders (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      In this paper we study the comprehensive effects on volume rendered images due to numerical errors caused by the use of finite precision for data representation and processing. To estimate actual error behavior we conduct ...
    • Evaluation of Cluster Identification Performance for Different PCP Variants 

      Holten, Danny; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Parallel coordinate plots (PCPs) are a well-known visualization technique for viewing multivariate data. In the past, various visual modifications to PCPs have been proposed to facilitate tasks such as correlation and ...
    • An Evaluation of Glyph Perception for Real Symmetric Traceless Tensor Properties 

      Jankun-Kelly, T. J.; Lanka, Yagneshwara; II, J. Edward Swan (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      A perceptual study of four tensor glyphs for symmetric, real, traceless tensors was performed. Each glyph encodes three properties of the system: Orientation, uniaxiality (alignment along the direction of orientation), and ...
    • An Exploratory Technique for Coherent Visualization of Time-varying Volume Data 

      Tikhonova, Anna; Correa, Carlos D.; Ma, Kwan-Liu (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      The selection of an appropriate global transfer function is essential for visualizing time-varying simulation data. This is especially challenging when the global data range is not known in advance, as is often the case ...
    • GraphDice: A System for Exploring Multivariate Social Networks 

      Bezerianos, Anastasia; Chevalier, Fanny; Dragicevic, Pierre; Elmqvist, Niklas; Fekete, Jean-Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Social networks collected by historians or sociologists typically have a large number of actors and edge attributes. Applying social network analysis (SNA) algorithms to these networks produces additional attributes such ...
