      Biopsies involve taking samples from living tissue using a biopsy needle. In current clinical practice they are a first mandatory step before any further medical actions are planned. Performing a biopsy on a deep seated ...
    • Visualization of 4D Blood-Flow Fields by Spatiotemporal Hierarchical Clustering 

      Pelt, Roy van; Jacobs, Sander; Romeny, Bart ter Haar; Vilanova, Anna (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Advancements in the acquisition and modeling of flow fields result in unsteady volumetric flow fields of unprecedented quality. An important example is found in the analysis of unsteady blood-flow data. Preclinical research ...
    • Drawing Large Graphs by Low-Rank Stress Majorization 

      Khoury, Marc; Hu, Yifan; Krishnan, Shankar; Scheidegger, Carlos (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Optimizing a stress model is a natural technique for drawing graphs: one seeks an embedding into Rd which best preserves the induced graph metric. Current approaches to solving the stress model for a graph with jVj ...
    • Semantic Wordification of Document Collections

      Word clouds have become one of the most widely accepted visual resources for document analysis and visualization, motivating the development of several methods for building layouts of keywords extracted from textual data. ...
    • Automatic Stream Surface Seeding: A Feature Centered Approach 

      Edmunds, Matt; Laramee, Robert S.; Malki, Rami; Masters, Ian; Croft, Nick; Chen, Guoning; Zhang, Eugene (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The ability to capture and visualize information within the flow poses challenges for visualizing 3D flow fields. Stream surfaces are one of many useful integration based techniques for visualizing 3D flow. However seeding ...
