Optical flow is the pattern of apparent motion of objects in a visual scene caused by the relative motion between an observer and the scene. There are many methods to extract optical flow, yet there is no platform that brings out comparison on the performance of these methods. In this paper, the comparison between the results obtained by the application of two major optical flow algorithms on different sets of image sequences is brought out. Also the applications of optical flow in vehicle detection and tracking are discussed.
