Purpose of the Study:

  • To present a novel active contour-based approach for object tracking.
  • To develop an algorithm that matches image region distributions to a model distribution.
  • To evaluate different distribution matching criteria for tracking accuracy.

Main Methods:

  • Utilizing active contours for object boundary delineation.
  • Modeling object characteristics using probability distributions (intensity, color, texture).
