Determination of optical flow and its discontinuities using non-linear diffusion

Abstract

A new method for optical flow computation by means of a coupled set of non-linear diffusion equations is presented. This approach integrates the classical differential approach with the correlation type of motion detectors. A measure of inconsistency within the optical flow field which indicates optical flow boundaries. This information is fed back to the optical flow equations in a non-linear way and allows the flow field to be reconstructed while preserving the discontinuities. The whole scheme is also applicable to stereo matching. The model is applied to a set of synthetic and real image sequences to illustrate the behaviour of the coupled diffusion equations.KeywordsOptical FlowNonlinear DiffusionStereo MatchOcclude RegionDual SchemeThese keywords were added by machine and not by the authors.
