      Liu, Baoquan; Clapworthy, Gordon J.; Dong, Feng (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Empty-space skipping is an essential acceleration technique for volume rendering. Image-order empty-space skipping is not well suited to GPU implementation, since it must perform checks on, essentially, a per-sample basis, ...

      We propose a novel out-of-core simplification and level-of-detail (LOD) volume rendering algorithm for large irregular grids represented as tetrahedral meshes. One important feature of our algorithm is that it creates a ...
    • Pathline: A Tool For Comparative Functional Genomics 

      Meyer, Miriah; Wong, Bang; Styczynski, Mark; Munzner, Tamara; Pfister, Hanspeter (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Biologists pioneering the new field of comparative functional genomics attempt to infer the mechanisms of gene regulation by looking for similarities and differences of gene activity over time across multiple species. They ...
    • The Perception of Correlation in Scatterplots 

      Rensink, Ronald A.; Baldridge, Gideon (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    • ProbExplorer: Uncertainty-guided Exploration and Editing of Probabilistic Medical Image Segmentation 

      Saad, Ahmed; Möller, Torsten; Hamarneh, Ghassan (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      In this paper, we develop an interactive analysis and visualization tool for probabilistic segmentation results in medical imaging. We provide a systematic approach to analyze, interact and highlight regions of segmentation ...
    • The Readability of Path-Preserving Clusterings of Graphs 

      Archambault, Daniel; Purchase, Helen C.; Pinaud, Bruno (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Graph visualization systems often exploit opaque metanodes to reduce visual clutter and improve the readability of large graphs. This filtering can be done in a path-preserving way based on attribute values associated with ...
    • Real-Time Temporal-Coherent Color Contrast Enhancement for Dichromats 

      Machado, Gustavo Mello; Oliveira, Manuel M. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We present an automatic image-recoloring technique for enhancing color contrast for dichromats whose computational cost varies linearly with the number of input pixels. Our approach can be efficiently implemented on GPUs, ...
    • Reusable Visualizations and Animations for Surgery Planning 

      Mühler, Konrad; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse ...
    • 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 ...
