    • Data-Driven Group Animation 

      Lai, Yu-Chi; Chenney, Stephen; Fan, Shaohua (University of Wisconsin-Madison Department of Computer Sciences, 2005)
      We introduce Data-Driven Groups (DDGs), an animation technique for groups of discrete agents, such as flocks, herds, or small crowds. DDGs are a natural extension of human motion graphs to groups. They create motion by ...
    • Quantification and Correction of Iris Color 

      Fan, Shaohua; Dyer, Charles; Hubbard, Larry (University of Wisconsin-Madison Department of Computer Sciences, 2003)
      A system has been developed that automatically extracts the iris region from photographs, computes the iris color in CIE u 'v ' diagram color space, and corrects the color based on a standard calibration target. This system ...
    • Sequential Monte Carlo Methods for Physically Based Rendering 

      Fan, Shaohua (University of Wisconsin-Madison Department of Computer Sciences, 2006)
      The goal of global illumination is to generate photo-realistic images by taking into account all of the light interactions in the scene. It does so by simulating light transport behaviors based on physical principles. ...
