    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 ...
  • 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)
    Today real-time sports performance analysis is a crucial aspect of matches in many major sports. For example, in soccer and rugby, team analysts may annotate videos during the matches by tagging specific actions and events, ...
  • 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 ...
  • I-SI: Scalable Architecture of Analyzing Latent Topical-Level Information From Social Media Data
