We present a novel method for visually monitoring a highway when the camera is relatively low to the ground and on the side of the road. In such a case, occlusion and the perspective effects due to the heights of the vehicles cannot be ignored. Features - We derive a concept called the relative height constraint that makes it possible ... Cars are well-separated (little to no occlusion) Can assume that all motion ...
