    In today s world, e-mail has become one of the most important means of communication in business and private lives due to its efficiency. However, the problems start as soon as mail volumes go beyond the scope of human ...
  • Discovering High-level Parameters for Visualization Design 

    Bhagavatula, Srinivas; Rheingans, Penny; Jardins, Marie des (The Eurographics Association, 2005)
    In most graphics and visualization applications, the effects of the mapping parameters on the output domain are multidimensional, non-linear and discontinuous. The complexity of such mapping often makes it difficult for a ...
  • Extending and Simplifying Transfer Function Design in Medical Volume Rendering Using Local Histograms 

    Lundström, Claes; Ljung, Patric; Ynnerman, Anders (The Eurographics Association, 2005)
    Direct Volume Rendering (DVR) is known to be of diagnostic value in the analysis of medical data sets. However, its deployment in everyday clinical use has so far been limited. Two major challenges are that the current ...
  • MoireTrees: Visualization and Interaction for Multi-Hierarchical Data 

    Mohammadi-Aragh, Mahnas Jean; Jankun-Kelly, T. J. (The Eurographics Association, 2005)
    Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies hierarchies with a single root element and a single path to each element. In contrast, ...
  • Version-Centric Visualization of Code Evolution 

    Voinea, S. Lucian; Telea, Alexandru; Chaudron, Michel (The Eurographics Association, 2005)
    The source code of software systems changes many times during the system lifecycle. We study how developers can get insight in these changes in order to understand the project context and the product artifacts. For this ...
  • Visualisation and Analysis of Large and Complex Scale-free Networks 

    Ahmed, Adel; Dywer, Tim; Hong, Seok-Hee; Murray, Colin; Song, Le; Wu, Ying Xin (The Eurographics Association, 2005)
    Scale-free networks appear in many application domains such as social and biological networks [BA99, BB03, BO04]. Roughly speaking, scale-free networks have power-law degree distribution, ultra-short average path length ...
  • Spline-Based Gradient Filters For High-Quality Refraction Computations in Discrete Datasets 

    Li, Shengying; Mueller, Klaus (The Eurographics Association, 2005)
    Based on the finding that refraction imposes significantly higher demands onto gradient filters than illumination and shading, we evaluate the family of spline filters as a good alternative to the cubic filters, which so ...
  • GVis: A Scalable Visualization Framework for Genomic Data 

    Hong, Jin; Jeong, Dong Hyun; Shaw, Chris D; Ribarsky, William; Borodovsky, Mark; Song, Chang (The Eurographics Association, 2005)
    This paper describes a framework we have developed for the visual analysis of large-scale phylogeny hierarchies populated with the genomic data of various organisms. This framework allows the user to quickly browse the ...
  • Visualization of Computer-Modeled Forests for Forest Management 

    Mohammadi-Aragh, Mahnas Jean; Fujisaki, Ikuko; Irby, Derek; Evans, David; Moorhead, Robert; Roberts, Scott (The Eurographics Association, 2005)
    Forest management is a costly and time-consuming activity. Remote sensing has the potential to improve the process by making it cheaper and more efficient, but only if appropriate characteristics can be determined from ...
  • Isosurface Extraction Using Fixed-Sized Buckets 

    Waters, Kenneth W.; Co, Christopher S.; Joy, Kenneth I. (The Eurographics Association, 2005)
    We present a simple and output optimal algorithm for accelerated isosurface extraction from volumetric data sets. Output optimal extraction algorithms perform an amount of work dominated by the size of the (output) isosurface ...
