Abstract

The elastic properties of real materials provide constraint on the types of non-rigid motion that can occur, and thus allow overconstrained estimates of 3-D non-rigid motion from optical flow data. It is shown that by modeling and simulating the physics of non-rigid motion it is possible to obtain good estimates of both object shape and velocity. Examples using grey-scale and X-ray imagery are presented, including an example of tracking a complex articulated figure.<<ETX>>
