      Uncertainties in flood predictions complicate the planning of mitigation measures. There is a consensus that many possible incident scenarios should be considered. For each scenario, a specific response plan should be ...
    • Methods for Compensating Contrast Effects in Information Visualization 

      Mittelstädt, Sebastian; Stoffel, Andreas; Keim, Daniel A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Color, as one of the most effective visual variables, is used in many techniques to encode and group data points according to different features. Relations between features and groups appear as visual patterns in the ...
    • Metro Transit-Centric Visualization for City Tour Planning 

      Claudio, Pio; Yoon, Sung-Eui (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In general, city trip planning consists of two main steps: knowing Points-Of-Interest (POIs), and then planning a tour route from the current point to next preferred POIs. We mainly consider the metro for traveling around ...
    • Networks of Names: Visual Exploration and Semi-Automatic Tagging of Social Networks from Newspaper Articles 

      Kochtchi, Artjom; Landesberger, Tatiana von; Biemann, Chris (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Understanding relationships between people and organizations by reading newspaper articles is difficult to manage for humans due to the large amount of data. To address this problem, we present and evaluate a new visual ...
    • Opacity Optimization for Surfaces 

      Günther, Tobias; Schulze, Maik; Esturo, Janick Martinez; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ...
    • Papilio: Visualizing Android Application Permissions 

      Loorak, Mona Hosseinkhani; Fong, Philip W. L.; Carpendale, Sheelagh (The Eurographics Association and John Wiley and Sons Ltd., 2014)
