Abstract
Traditionally, image motion and its approximation known as optical flow have been treated as continuous functions of the image domain [9]. However, in realistic imagery, one finds cases verifying this hypothesis exceedingly rarely. Many phenomena may cause discontinuities in the optical flow function of imagery [16]. 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 [8] such as motion segmentation [1] and 3-d surface reconstruction [17].
