Aiming at the problem of preserving the discontinuities in optical flow field for motion segmentation

a meaningful research has been done. The key of the research focuses on the improvement of the diffusion tensor in reaction-diffusion model. By analyzing the existing methods

we proposed a new method which design diffusion tensor by joint image- & flow- driven. Furthermore an efficient coarse-to-fine numerical scheme about the partial differential equation has been present at the same time. our experiments proved that our proposed approach can effectively overcome the motion blur problem of other methods while and preserving the discontinuities in the optic flow field more accurately.
