  • Articulated Pose Estimation in a Learned Smooth Space of Feasible Solutions
    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 ...
  • Multi-Scale 3D Scene Flow from Binocular Stereo Sequences
    Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2007-06)
    Scene flow methods estimate the three-dimensional motion field for points in the world, using multi-camera video data. Such methods combine multi-view reconstruction with motion estimation. This paper describes an alternative ...
  • Multi-scale 3D Scene Flow from Binocular Stereo Sequences
    Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2004-11-02)
    Scene flow methods estimate the three-dimensional motion field for points in the world, using multi-camera video data. Such methods combine multi-view reconstruction with motion estimation approaches. This paper describes ...
  • Simultaneous Learning of Non-Linear Manifold and Dynamical Models for High-Dimensional Time Series
    Li, Rui (Boston University Computer Science Department, 2009-08-10)
    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 ...
  • Simultaneous Learning of Nonlinear Manifold and Dynamical Models for High-dimensional Time Series
    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 ...
  • Tracking Human Body Pose on a Learned Smooth Space
    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 ...
