• Image Segmentation Using Active Contours Driven by the Bhattacharyya Gradient Flow 

      Michailovich, Oleg V.; Rathi, Yogesh; Tannenbaum, Allen R. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2007-11)
      This paper addresses the problem of image segmentation by means of active contours, whose evolution is driven by the gradient flow derived froman energy functional that is based on the Bhattacharyya distance. In particular, ...
    • Kernel-based high-dimensional histogram estimation for visual tracking 

      Karasev, Peter; Malcolm, James G.; Tannenbaum, Allen R. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-10)
      We propose an approach for non-rigid tracking that represents objects by their set of distribution parameters. Compared to joint histogram representations, a set of parameters such as mixed moments provides a significantly ...
