Calculus of Variational Optical Flow Based on Structure-dependent Regularization

The traditional calculus of variational optical flow is mainly based on various characteristic constancy assumptions and smoothness assumptions.There are serious errors in dealing with image noise,edges,shadow,illumination changes,especially the edges and illumination changes.An improved calculus of variational optical flow is proposed in this paper.The data term is to solve the problem of illumination changes by the combination of gray and gradient constancy assumption.The smoothness term related with structure-dependent regularization is introduced,which can inhibit the edges of moving objects in the "drift" phenomenon effectively by weakening the efforts of smooth term in the boundaries of the moving objects and increasing the punishment of gradient.Experimental results show that this calculus is suitable and effective.
