Abstract
Standard approaches to motion analysis assume
that the optic ow is smooth; such techniques have
trouble dealing with occlusion boundaries. The most
popular solution is to allow discontinuities in the ow
eld, imposing the smoothness constraint in a piece-
wise fashion. But there is a sense in which the dis-
continuities in ow are artifactual, resulting from the
attempt to capture the motion of multiple overlapping
objects in a single ow eld. Instead we can decom-
pose the image sequence into a set of overlapping lay-
