    • Anatomy-Guided Multi-Level Exploration of Blood Flow in Cerebral Aneurysms 

      Neugebauer, Mathias; Janiga, Gabor; Beuing, Oliver; Skalej, Martin; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      For cerebral aneurysms, the ostium, the area of inflow, is an important anatomic landmark, since it separates the pathological vessel deformation from the healthy parent vessel. A better understanding of the inflow ...

    • Dynamic Insets for Context-Aware Graph Navigation 

      Ghani, Sohaib; Riche, N. Henry; Elmqvist, Niklas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Maintaining both overview and detail while navigating in graphs, such as road networks, airline route maps, or social networks, is difficult, especially when targets of interest are located far apart. We present a navigation ...

    • A Gradient-Based Comparison Measure for Visual analysis of Multifield Data 

      Nagaraj, Suthambhara; Natarajan, Vijay; Nanjundiah, Ravi S. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We introduce a multifield comparison measure for scalar fields that helps in studying relations between them. The comparison measure is insensitive to noise in the scalar fields and to noise in their gradients. Further, ...

    • PaperVis: Literature Review Made Easy 

      Chou, Jia -Kai; Yang, C. -K. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Reviewing literatures for a certain research field is always important for academics. One could use Google-like information seeking tools, but oftentimes he/she would end up obtaining too many possibly related papers, as ...

    • Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow 

      Baer, Alexandra; Gasteiger, Rocco; Cunningham, Douglas; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ...

    • Piecewise Laplacian-based Projection for Interactive Data Exploration and Organization 

      Paulovich, Fernando V.; Eler, D. M.; Poco, J.; Botha, Charl P.; Minghim, R.; Nonato, L. G. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Multidimensional projection has emerged as an important visualization tool in applications involving the visual analysis of high-dimensional data. However, high precision projection methods are either computationally ...

    • Prostate Cancer Visualization from MR Imagery and MR Spectroscopy 

      Marino, Joseph; Kaufman, Arie (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Prostate cancer is one of the most prevalent cancers among males, and the use of magnetic resonance imaging (MRI) has been suggested for its detection. A framework is presented for scoring and visualizing various MR data ...

    • Semantic-Preserving Word Clouds by Seam Carving 

      Wu, Yingcai; Provan, Thomas; Wei, Furu; Liu, Shixia; Ma, Kwan-Liu (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Word clouds are proliferating on the Internet and have received much attention in visual analytics. Although word clouds can help users understand the major content of a document collection quickly, their ability to visually ...

    • A Shader Framework for Rapid Prototyping of GPU-Based Volume Rendering 

      Rieder, Christian; Palmer, Stephan; Link, Florian; Hahn, Horst K. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important ...

    • Visual Boosting in Pixel-based Visualizations 

      Oelke, Daniela; Janetzko, Halldor; Simon, Svenja; Neuhaus, Klaus; Keim, Daniel A. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Pixel-based visualizations have become popular, because they are capable of displaying large amounts of data and at the same time provide many details. However, pixel-based visualizations are only effective if the data set ...

    • Visualizing High-Dimensional Structures by Dimension Ordering and Filtering using Subspace Analysis 

      Ferdosi, Bilkis J. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      High-dimensional data visualization is receiving increasing interest because of the growing abundance of highdimensional datasets. To understand such datasets, visualization of the structures present in the data, such as ...
