    • 3D Soft Segmentation and Visualization of Medical Data Based on Nonlinear Diffusion and Distance Functions 

      Petersch, B.; Serrano-Serrano, O.; Hönigmann, D. (The Eurographics Association, 2006)
      Visualization of medical 3D data is a complex problem, since the raw data is often unsuitable for standard techniques like Direct Volume Rendering. Some kind of pre-treatment is necessary, usually segmentation of the ...
    • Affiliation Dynamics with an Application to Movie-Actor Biographies 

      Brandes, Ulrik; Hoefer, Martin; Pich, Christian (The Eurographics Association, 2006)
      We propose a visualization approach for dynamic affiliation networks in which events are characterized by a set of descriptors. It uses a radial ripple metaphor to display the passing of time and conveys relations among ...

      Lundström, Claes; Ynnerman, Anders; Ljung, Patric; Persson, Anders; Knutsson, Hans (The Eurographics Association, 2006)
      The high complexity of Transfer Function (TF) design is a major obstacle to widespread routine use of Direct Volume Rendering, particularly in the case of medical imaging. Both manual and automatic TF design schemes would ...

      ereda, Petr; Vilanova, Anna; Gerritsen, Frans A. (The Eurographics Association, 2006)
      Transfer function design plays a crucial role in direct volume rendering. Furthermore, it has a major influence on the efficiency of the visualization process. We have developed a framework that facilitates the semi-automatic ...
    • A Case Study: Visualizing Material Point Method Data 

      Bigler, James; Guilkey, James; Gribble, Christiaan; Hansen, Charles; Parker, Steven G. (The Eurographics Association, 2006)
      The Material Point Method is used for complex simulation of solid materials represented using many individual particles. Visualizing such data using existing polygonal or volumetric methods does not accurately encapsulate ...
    • Combining Extended Table Lens and Treemap Techniques for Visualizing Tabular Data 

      Telea, Alexandru (The Eurographics Association, 2006)
      We present a framework for visualizing large tabular data that combines two views: the table view and the treemap view. The table view extends the known table lens as follows: We cluster related elements to reduce subsampling ...
    • CVSgrab: Mining the History of Large Software Projects 

      Voinea, S. L.; Telea, A. (The Eurographics Association, 2006)
      Many software projects use Software Configuration Management systems to support their development process. Such systems accumulate in time large amounts of information useful for process accounting and auditing. We study ...
    • D2VR: High-Quality Volume Rendering of Projection-based Volumetric Data 

      Rautek, Peter; Csébfalvi, Balázs; Grimm, Sören; Bruckner, Stefan; Gröller, Eduard (The Eurographics Association, 2006)
      Volume rendering techniques are conventionally classified as either direct or indirect methods. Indirect methods require to transform the initial volumetric model into an intermediate geometrical model in order to efficiently ...
    • Data Reconstruction and Visualization Techniques for Forensic Pathology 

      Ehlert, Alexander; Salah, Zein; Bartz, Dirk (The Eurographics Association, 2006)
      Forensic pathology is largely concerned with the determination of the cause and manner of deaths after accidents, or other circumstances in criminal investigations. A major task in that process is the documentation of ...
    • Direct Isosurface Extraction from Scattered Volume Data 

      Rosenthal, Paul; Linsen, Lars (The Eurographics Association, 2006)
      Isosurface extraction is a standard visualization method for scalar volume data and has been subject to research for decades. Nevertheless, to our knowledge, no isosurface extraction method exists that directly extracts ...
    • Efficient Surface Reconstruction from Noisy Data using Regularized Membrane Potentials 

      Jalba, A. C.; Roerdink, J. B. T. M. (The Eurographics Association, 2006)
      We present a novel, physically-motivated method for surface reconstruction that can recover smooth surfaces from noisy and sparse data sets, without using orientation information. A new volumetric technique based on ...
    • Enhanced Visualizations of Thermographic Data in Process Industry 

      Seipel, S.; Forsberg, A.- K.; Wesslén, D. (The Eurographics Association, 2006)
