    A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data 

    Tzeng, Fan-Yin; Ma, Kwan-Liu (The Eurographics Association, 2004)
    In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ...

    Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery 

    Wang, Yue; Teoh, Soon Tee; Ma, Kwan-Liu (The Eurographics Association, 2006)
    User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ...

    Natural Visualizations 

    Haroz, Steve; Ma, Kwan-Liu (The Eurographics Association, 2006)
    This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ...

    High-Quality Lighting and Efficient Pre-Integration for Volume Rendering 

    Lum, Eric B.; Wilson, Brett; Ma, Kwan-Liu (The Eurographics Association, 2004)
    Pre-integrated volume rendering is an effective technique for generating high-quality visualizations. The precomputed lookup tables used by this method are slow to compute and can not include truly pre-integrated lighting ...

    High-Quality Rendering of Compressed Volume Data Formats 

    Fout, Nathaniel; Akiba, Hiroshi; Ma, Kwan-Liu; Lefohn, Aaron E.; Kniss, Joe (The Eurographics Association, 2005)
    Rendering directly from packed or compressed volume data formats using graphics hardware has advantages in terms of memory consumption and bandwidth, but results in lower-quality images due to the prohibitive cost of ...

    A Tri-Space Visualization Interface for Analyzing Time-Varying Multivariate Volume Data 

    Akiba, Hiroshi; Ma, Kwan-Liu (The Eurographics Association, 2007)
    The dataset generated by a large-scale numerical simulation may include thousands of timesteps and hundreds of variables describing different aspects of the modeled physical phenomena. In order to analyze and understand ...

    Path Visualization for Adjacency Matrices 

    Shen, Zeqian; Ma, Kwan-Liu (The Eurographics Association, 2007)
    For displaying a dense graph, an adjacency matrix is superior than a node-link diagram because it is more compact and free of visual clutter. A node-link diagram, however, is far better for the task of path finding because ...

    Simultaneous Classification of Time-Varying Volume Data Based on the Time Histogram 

    Akiba, Hiroshi; Fout, Nathaniel; Ma, Kwan-Liu (The Eurographics Association, 2006)
    An important challenge in the application of direct volume rendering to time-varying data is the specification of transfer functions for all time steps. Very little research has been devoted to this problem, however. To ...

    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 ...
