Computer Analysis of Planar Curvilinear Moving Images

The present correspondence develops an algorithm for tracking the motion of planar curvilinear moving objects from a sequence of scenes produced by a television camera. The shape of the objects is unrestricted except that holes may not be present. The shape of the objects may vary slightly from scene to scene. The linear and angular velocities of the objects are computed, and a model is created and updated each time a new scene is processed. Furthermore, the algorithm generates a prediction of each successive input scene. The algorithm is implemented in the computer language Lisp, and experimental results are presented.
