Medical image registration method based on the optical flow model of improved regularization

Compared with other registration methods, the registration method based on initial optical flow model can obtain the quick registration speed. However because of their own drawbacks, the registration images are too vague. Therefore in this paper we improve the regularization term in initial optical flow model. The improve regularization term reduced the blurring of initial optical flow model. The experiment results show that the new method can achieve more accurate registration results and high efficiency.
