| Abstract: | This paper looks further at the method of medical image patching based on mutual information. We have compared the methods of density estimation with the searching strategy of image registration. At the same time, a new way of image preprocessing based on grads information has been used as well as a novel display method, which introduced directions of the edge curve into image interpolation. A good patching result has been made in our scheme. |
