A Warp-Based Feature Tracker

We present the warp tracker, a new system for tracking features through a sequence of images. Employing an automated multi-resolution lattice deformation technique, the warp tracker performs fairly well on its own, and its hierarchical nature naturally lends itself to being integrated with other tracking algorithms for increased accuracy and robustness. Developed specifically for use in next-generation video teleconferencing systems, a prototype of the warp tracker has already been tested on tracking human eyes with encouraging results.
