Many problems in motion can be approached by focusing attention on events in the motion of objects. Our concept of event is the very general one of any discontinuity in consistent motion. This paper addresses the use of low-level events comprising discontinuities in the regular consistent motions of feature points. For the experiments described here, events are changes in the parameters of uniformly accelerated motion: acceleration, velocity, and initial position. We then use the detected events and the concept of path coherence to achieve a correspondence that describes the motion of objects over many frames. The correspondence mechanism seeks to minimize the number of events.
