    • A Framework for the Multi-Temporal Analysis of Land Cover Change using Visual Analytics 

      Kinkeldey, C.; Schiewe, J. (The Eurographics Association, 2011)
      Land cover change analysis serves as a basis for planning processes in a wide range of applications. For this task, the use of remote sensing data has become more popular over the last decades. However, despite much research ...

    • Contingency Wheel: Visual Analysis of Large Contingency Tables 

      Alsallakh, Bilal; Groeller, Eduard; Miksch, Silvia; Suntinger, Martin (The Eurographics Association, 2011)
      We present the Contingency Wheel, a visual method for finding and analyzing associations in a large nxm contingency table with m less than 100 and n being two to three orders of magnitude larger than m. The method is ...

    • Characterizing Visual Analytics in Diagnostic Imaging 

      Lundström, C.; Persson, A. (The Eurographics Association, 2011)
      Many necessary and desired improvements in healthcare are dependent on progress in medical imaging. As shown in this paper, the challenges targeted by visual analytics (VA) coincide with main challenges for radiologists' ...

    • Adaptive Interactive Multi-Resolution Computational Steering for Complex Engineering Systems 

      Matkovic, K.; Gracanin, D.; Jelovic, M.; Cao, Y. (The Eurographics Association, 2011)
      Computational steering integrates modeling, computation, data analysis, visualization, and data input components of a simulation. Since the simulation space is, in general, very large and continuous, selecting discrete ...

    • Steerable Clustering for Visual Analysis of Ecosystems 

      Ahmed, Zafar; Yost, Patrick; McGovern, Amy; Weaver, Chris (The Eurographics Association, 2011)
      One of the great challenges in the geosciences is understanding ecological systems in order to predict changes and responses in space and time at scales from local to global. Ecologists are starting to recognize the value ...

    • Understanding the Role and Value of Interaction: First Steps 

      Aigner, W. (The Eurographics Association, 2011)
      Visual Analytics strongly emphasizes the importance of interaction. However, until now, interaction is only sparingly treated as subject matter on its own. How and why interactivity is beneficial to gain insight and make ...

    • Exploring Complex Mobile Life through Lightweight Visualizations 

      Kim, Tanyoung; Blom, Jan; Stasko, John (The Eurographics Association, 2011)
      Smart phones can be used to collect various types of data from a user spanning call and text message logs to GPS coordinates, and to Bluetooth detection. These data are indicative of behavior across various socio-temporalspatial ...

    • Towards a Concept how the Structure of Time can Support the Visual Analytics Process 

      Lammarsch, T.; Aigner, W.; Bertone, A.; Miksch, S.; Rind, A. (The Eurographics Association, 2011)
      The primary goal of Visual Analytics (VA) is the close intertwinedness of human reasoning and automated methods. An important task for this goal is formulating a description for such a VA process. We propose the design of ...

    • Interactive Analysis of Object Group Changes over Time 

      Bremm, S.; Landesberger, T. von; Andrienko, G.; Andrienko, N.; Schreck, Tobias (The Eurographics Association, 2011)
      The analysis of time-dependent data is an important task in various application domains. Often, the analyzed data objects belong to groups. The group memberships may stem from natural arrangements (e.g., animal herds), or ...

    • SmartStripes - Looking under the Hood of Feature Subset Selection Methods 

      May, T.; Davey, J.; Ruppert, T. (The Eurographics Association, 2011)
      We propose a visualization method for the diagnosis and interactive refinement of automatic techniques for feature subset selection. So-called filter techniques use statistical ranking measures to identify the most useful ...

    • Visual Comparison of Ranked Result Cumulated Gains 

      Ferro, N.; Sabetta, A.; Santucci, G.; Tino, G.; Veltri, F. (The Eurographics Association, 2011)
      Ranking is fundamental in Information Retrieval (IR) and several measures have been developed over the years to assess the quality of a ranked result list, such as those based on the idea of computing the cumulative gain ...

    • Visual Analysis of Advanced Manufacturing Simulations 

      Wörner, M.; Ertl, T. (The Eurographics Association, 2011)
      Today's manufacturing companies are faced with requests for highly customer-specific products that come in numerous variants but small numbers of units per variant. Therefore, their manufacturing processes need to be ...

    • Visual Analysis of User Behaviour in Pay-Per-Bid Auctions 

      Walker, Rick; Cenydd, Llyr ap; Pop, Serban; Roberts, Jonathan C. (The Eurographics Association, 2011)
      In pay-per-bid auctions, placing a bid costs a fee, and only raises the price of the item by a small increment. At the conclusion of the auction, the last bidder wins, and the price paid by the winning bidder is subsidised ...

    • Data Driven Color Mapping 

      Eisemann, Martin; Albuquerque, Georgia; Magnor, Marcus (The Eurographics Association, 2011)
      In this paper we present a simple, yet effective method to map data set values of different distributions to a color map in order to reveal interesting structures. We make use of an ordering and a simple projection technique ...
