A theory of occlusion in the context of optical flow
Traditionally, image motion and its approximation known as optical flow have been treated as continuous functions of the image domain . However, in realistic imagery, one finds cases verifying this hypothesis exceedingly rarely. Many phenomena may cause discontinuities in the optical flow function of imagery . Among them, occlusion and translucency are frequent causes of discontinuities in realistic imagery. In addition, their information content is useful to later stages of processing  such as motion segmentation  and 3-d surface reconstruction .
