    • A Salience-based Quality Metric for Visualization 

      Jänicke, Heike; Chen, Min (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ...
    • Scalable Multi-view Registration for Multi-Projector Displays on Vertically Extruded Surfaces 

      Sajadi, Behzad; Majumder, Aditi (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Recent work have shown that it is possible to register multiple projectors on non-planar surfaces using a single uncalibrated camera instead of a calibrated stereo pair when dealing with a special class of non-planar ...
    • SmallWorlds: Visualizing Social Recommendations 

      Gretarsson, Brynjar; O'Donovan, John; Bostandjiev, Svetlin; Hall, Christopher; Höllerer, Tobias (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present SmallWorlds, a visual interactive graph-based interface that allows users to specify, refine and build item-preference profiles in a variety of domains. The interface facilitates expressions of taste through ...
    • Space-in-Time and Time-in-Space Self-Organizing Maps for Exploring Spatiotemporal Patterns 

      Andrienko, Gennady; Andrienko, Natalia; Bremm, Sebastian; Schreck, Tobias; Landesberger, Tatiana von; Bak, Peter; Keim, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Spatiotemporal data pose serious challenges to analysts in geographic and other domains. Owing to the complexity of the geospatial and temporal components, this kind of data cannot be analyzed by fully automatic methods ...
    • Streaming-Enabled Parallel Dataflow Architecture for Multicore Systems 

      Vo, Huy T.; Osmari, Daniel K.; Summa, Brian; Comba, João L. D.; Pascucci, Valerio; Silva, Cláudio T. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We propose a new framework design for exploiting multi-core architectures in the context of visualization dataflow systems. Recent hardware advancements have greatly increased the levels of parallelism available with all ...
    • Supporting Exploratory Analysis with the Select and Slice Table 

      Shrinivasan, Yedendra B.; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      In interactive visualization, selection techniques such as dynamic queries and brushing are used to specify and extract items of interest. In other words, users define areas of interest in data space that often have a clear ...
    • Topographic Map Visualization from Adaptively Compressed Textures 

      Andujar, Carlos (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Raster-based topographic maps are commonly used in geoinformation systems to overlay geographic entities on top of digital terrain models. Using compressed texture formats for encoding topographic maps allows reducing ...
    • Topological Landscape Ensembles for Visualization of Scalar-Valued Functions 

      Harvey, William; Wang, Yusu (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Visual representation techniques enable perception and exploration of scientific data. Following the topological landscapes metaphor ofWeber et al., we provide a new algorithm for visualizing scalar functions defined on ...
    • Topology Aware Stream Surfaces 

      Schneider, Dominic; Reich, Wieland; Wiebel, Alexander; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the ...
    • Topology-based Smoothing of 2D Scalar Fields with C1-Continuity 

      Weinkauf, Tino; Gingold, Yotam; Sorkine, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Data sets coming from simulations or sampling of real-world phenomena often contain noise that hinders their processing and analysis. Automatic filtering and denoising can be challenging: when the nature of the noise is ...
    • Toward a Lagrangian Vector Field Topology 

      Fuchs, Raphael; Peikert, Ronny; Kemmler, Jan; Schindler, Benjamin; Waser, Juergen; Sadlo, Filip; Hauser, Helwig (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      In this paper we present an extended critical point concept which allows us to apply vector field topology in the case of unsteady flow.We propose a measure for unsteadiness which describes the rate of change of the ...
    • Understanding Interactive Legends: a Comparative Evaluation with Standard Widgets 

      Riche, Nathalie Henry; Lee, Bongshin; Plaisant, Catherine (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Interactive information visualization systems rely on widgets to allow users to interact with the data and modify the representation. We define interactive legends as a class of controls combining the visual representation ...
    • Video Visualization for Snooker Skill Training 

      Höferlin, Markus; Grundy, Edward; Borgo, Rita; Weiskopf, Daniel; Chen, Min; Griffiths, Iwan W.; Griffiths, W. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present a feasibility study on using video visualization to aid snooker skill training. By involving the coaches and players in the loop of intelligent reasoning, our approach addresses the difficulties of automated ...
    • Visual Analysis of Multi-Joint Kinematic Data 

      Krekel, Peter R.; Valstar, Edward R.; Groot, Jurriaan de; Post, Frits H.; Nelissen, Rob G. H. H.; Botha, Charl P. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Kinematics is the analysis of motions without regarding forces or inertial effects, with the purpose of understanding joint behaviour. Kinematic data of linked joints, for example the upper extremity, i.e. the shoulder and ...
