  • Tian, Tai-Peng; Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2005-07-07)
    A learning based framework is proposed for estimating human body pose from a single image. Given a differentiable function that maps from pose space to image feature space, the goal is to invert the process: estimate the ...
  • Tian, Tai-Peng; Sclaroff, Stan (CS Department, Boston University, 2010-03-31)
    This paper presents an algorithm for recovering the globally optimal 2D human figure detection using a loopy graph model. This is computationally challenging because the time complexity scales exponentially in the size of ...
  • Tian, Tai-Peng; Sclaroff, Stan (Boston University Computer Science Department, 2004-11-04)
    Hand signals are commonly used in applications such as giving instructions to a pilot for airplane take off or direction of a crane operator by a foreman on the ground. A new algorithm for recognizing hand signals from a ...
  • Li, Rui; Tian, Tai-Peng; Sclaroff, Stan (Boston University Computer Science Department, 2007-08)
    The goal of this work is to learn a parsimonious and informative representation for high-dimensional time series. Conceptually, this comprises two distinct yet tightly coupled tasks: learning a low-dimensional manifold and ...
  • Tian, Tai-Peng; Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2005-07-28)
    Particle filtering is a popular method used in systems for tracking human body pose in video. One key difficulty in using particle filtering is caused by the curse of dimensionality: generally a very large number of particles ...
