    • Integrating Local Feature Detectors in the Interactive Visual Analysis of Flow Simulation Data 

      Buerger, Raphael; Muigg, Philipp; Ilcík, Martin; Doleisch, Helmut; Hauser, Helwig (The Eurographics Association, 2007)
      We present smooth formulations of common vortex detectors that allow a seamless integration into the concept of interactive visual analysis of flow simulation data. We express the originally binary feature detectors as ...

    • See What You Know: Analyzing Data Distribution to Improve Density Map Visualization 

      Bertini, Enrico; Girolamo, Alessio Di; Santucci, Giuseppe (The Eurographics Association, 2007)
      Density maps allow for visually rendering density differences, usually mapping density values to a grey or color scale. The paper analyzes the drawbacks arising from the commonly used strategies and introduces a novel ...

    • Sonar Explorer: A New Tool for Visualization of Fish Schools from 3D Sonar Data 

      Balabanian, Jean-Paul; Viola, Ivan; Ona, Egil; Patel, Ruben; Groeller, Eduard (The Eurographics Association, 2007)
      We present a novel framework for analysis and visualization of fish schools in 3D sonar surveys. The 3D sonar technology is new and there have not been applications to visualize the data in 3D. We have created an application ...

    • The CoMIRVA Toolkit for Visualizing Music-Related Data 

      Schedl, Markus; Knees, Peter; Seyerlehner, Klaus; Pohle, Tim (The Eurographics Association, 2007)
      We present CoMIRVA, which is an abbreviation for Collection of Music Information Retrieval and Visualization Applications. CoMIRVA is a Java framework and toolkit for information retrieval and visualization. It is licensed ...

    • Subdivision Volume Splatting 

      McDonnell, Kevin T.; Neophytou, Neophytos; Mueller, Klaus; Qin, Hong (The Eurographics Association, 2007)
      Volumetric Subdivision (VS) is a powerful paradigm that enables volumetric sculpting and realistic volume deformations that give rise to the concept of "virtual clay". In VS, volumes are commonly represented as a space-filling ...

    • Design of Multi-dimensional Transfer Functions Using Dimensional Reduction 

      Pinto, Francisco de Moura; Freitas, Carla M. D. S. (The Eurographics Association, 2007)
      Direct volume rendering techniques allow visualization of volume data without extracting intermediate geometry. The mapping from voxel attributes to optical properties is performed by transfer functions which, consequently, ...

    • A Tri-Space Visualization Interface for Analyzing Time-Varying Multivariate Volume Data 

      Akiba, Hiroshi; Ma, Kwan-Liu (The Eurographics Association, 2007)
      The dataset generated by a large-scale numerical simulation may include thousands of timesteps and hundreds of variables describing different aspects of the modeled physical phenomena. In order to analyze and understand ...

    • Interactive Visualization of Multi-Field Medical Data Using Linked Physical and Feature-Space Views 

      Blaas, Jorik; Botha, Charl P.; Post, Frits H. (The Eurographics Association, 2007)
      Multi-field datasets contain multiple parameters defined over the same spatio-temporal domain. In medicine, such multi-field data is being used more often every day, and there is an urgent need for exploratory visualization ...

    • Dimensional Congruence for Interactive Visual Data Mining and Knowledge Discovery 

      Baumgaertner, Sebastian; Ebert, Achim; Deller, Matthias (The Eurographics Association, 2007)
      Many authors in the field of 3D human computer interaction have described the advantages of 3D user interfaces: Intuitive metaphors from daily life, immersive workspaces, virtual environments that closely resemble natural ...

    • TrustNeighborhoods: Visualizing Trust in Distributed File Sharing Systems 

      Elmqvist, Niklas; Tsigas, Philippas (The Eurographics Association, 2007)
      We present TrustNeighborhoods, a security trust visualization for situational awareness on the Internet aimed at novice and intermediate users of a distributed file sharing system. The TrustNeighborhoods technique uses the ...

    • Online Dynamic Graph Drawing 

      Frishman, Yaniv; Tal, Ayellet (The Eurographics Association, 2007)
      This paper presents an algorithm for drawing a sequence of graphs online. The algorithm strives to maintain the global structure of the graph and thus the user's mental map, while allowing arbitrary modifications between ...

    • Path Visualization for Adjacency Matrices 

      Shen, Zeqian; Ma, Kwan-Liu (The Eurographics Association, 2007)
      For displaying a dense graph, an adjacency matrix is superior than a node-link diagram because it is more compact and free of visual clutter. A node-link diagram, however, is far better for the task of path finding because ...

    • Grouse: Feature-Based, Steerable Graph Hierarchy Exploration 

      Archambault, Daniel; Munzner, Tamara; Auber, David (The Eurographics Association, 2007)
      Grouse is a feature-based approach to steerable exploration of a graph and an associated hierarchy. Steerability allows exploration to begin immediately, rather than requiring a costly layout of the entire graph as an ...

    • Story Telling for Presentation in Volume Visualization 

      Wohlfart, Michael; Hauser, Helwig (The Eurographics Association, 2007)
      In this paper we present a novel approach to volume visualization for presentation purposes that improves both the comprehensibility and credibility of the intended visualization message. Therefore, we combine selected ...

    • Manual Clustering Refinement using Interaction with Blobs 

      Heine, Christian; Scheuermann, Gerik (The Eurographics Association, 2007)
      The huge amount of different automatic clustering methods emphasizes one thing: there is no optimal clustering method for all possible cases. In certain application domains, like genomics and natural language processing, ...

    • Visualization of Uncertainty in Lattices to Support Decision-Making 

      Collins, Christopher; Carpendale, Sheelagh; Penn, Gerald (The Eurographics Association, 2007)
      Lattice graphs are used as underlying data structures in many statistical processing systems, including natural language processing. Lattices compactly represent multiple possible outputs and are usually hidden from users. ...

    • KeyStrokes: Personalizing Typed Text with Visualization 

      Neumann, Petra; Tat, Annie; Zuk, Torre; Carpendale, Sheelagh (The Eurographics Association, 2007)
      With the ubiquity of typed text, the style and much of the personality of handwriting has been lost from general communication. To counter this we introduce an artistic real-time visualization of typed messages that ...
