| Abstract(in English) | It is a important research field in computer vision to extract optical flow form sequential images,and many algorithms have been proposed.Especially the gradient method that Horn proposed has the advantage of being able to extract optical flow only by numeraical calculation.However in the constranit of the gradient method,only parallel translation is considered.We introduce the affine transform so as to obtain constraint consdering rotate and scale change tranforms.Experimental results show the validity of this method by use of synthesized images.And we discuss about extracting optical flow in a case of occuring parallel,scale change and rotate transforms simultaneously |
