Visual tracking with deformation models
James Matthew Rehg, Andrew Witkin · 2002
A novel solution to the 2-D tracking problem is presented. This solution has two major components: a deformation model that constrains the interpretation of motion, and a set of energy-based match criteria that specify image features to be used in tracking. The separation of the motion model from the match features is an advantage of this approach over previous tracking systems. An implementation of these ideas has been shown to exhibit fast and flexible operation over a wide class of image motions. Experimental results are given for two real-world image sequences.>
