      Wang, Lei; Kaufman, Arie (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      This paper introduces an automatic color design method that is driven by an importance function of the objects within a volumetric dataset. Our method allows the user to intuitively modify the object classification and the ...

    • Automating Transfer Function Design with Valley Cell-Based Clustering of 2D Density Plots 

      Wang, Yunhai; Zhang, Jian; Lehmann, Dirk J.; Theisel, Holger; Chi, Xuebin (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Two-dimensional transfer functions are an effective and well-accepted tool in volume classification. The design of them mostly depends on the user's experience and thus remains a challenge. Therefore, we present an approach ...

    • ConnectedCharts: Explicit Visualization of Relationships between Data Graphics 

      Viau, Christophe; McGuffin, Michael (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Multidimensional multivariate data can be visualized using many different well-known charts, such as bar charts, stacked bar charts, grouped bar charts, scatterplots, or pivot tables, or also using more advanced highdimensional ...

      We present a general visual analytics architecture that is designed and implemented to effectively analyze unstructured social media data on a large scale. Pipelined on a high-performance cluster configuration, MPI processing, ...

    • PORGY: A Visual Graph Rewriting Environment for Complex Systems 

      Pinaud, Bruno; Melançon, Guy; Dubois, Jonathan (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Graph rewriting systems (GRSs) operate on graphs by substituting local patterns according to a set of rewriting rules. The apparent simplicity of GRSs hides an incredible complexity and turns the study of these systems ...

    • MatchPad: Interactive Glyph-Based Visualization for Real-Time Sports Performance Analysis 

      Legg, Philip; Chung, David H. S.; Parry, Matthew L.; Jones, Mark W.; Long, Rhys; Griffiths, Iwan W.; Chen, Min (The Eurographics Association and Blackwell Publishing Ltd., 2012)
