      We propose a new framework design for exploiting multi-core architectures in the context of visualization dataflow systems. Recent hardware advancements have greatly increased the levels of parallelism available with all ...
    • Scalable Multi-view Registration for Multi-Projector Displays on Vertically Extruded Surfaces 

      Sajadi, Behzad; Majumder, Aditi (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Recent work have shown that it is possible to register multiple projectors on non-planar surfaces using a single uncalibrated camera instead of a calibrated stereo pair when dealing with a special class of non-planar ...
    • An Interactive Visual Analytics System for Bridge Management 

      Wang, Xiaoyu; Dou, Wenwen; Chen, Shen-En; Ribarsky, William; Chang, Remco (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      Bridges deteriorate over their life cycles and require continuous maintenance to ensure their structural integrity, and in turn, the safety of the public. Maintaining bridges is a multi-faceted operation that requires both ...
