Abstract : This paper presents a mechanism for dealing with incorrect motion estimation in degraded post production image sequences. This tends to be caused by Pathological Motion (a combination of motion blur, complex foreground motion, shadows etc). We describe a method for estimating where such regions are likely to occur by segmenting sequences into foreground and background motion. We show it is possible to produce a conservative matte of which regions in a sequence are foreground, and that blotch detection can be adapted accordingly in such areas.
