Abstract:

This paper proposes an optical flow field registration method with window function for the non-rigid medical image.These methods control image's fuzzy degrees by adjusting the window function to.By adopting image pyramidal decomposition the problem that the Horn optical flow field cannot deal with large displacement is solved.Experimental results show that the method can satisfy the medical image's requirement for registration accuracy and has high efficiency.

Key words: non-rigid registration;optical flow field;window procedure
