SIFT is an excellent descriptor to features in medical images.However, the algorithm to achieve SIFT is tedious and takes a long time.To cope with this, we combined image integration and image region partition and proposed a modified SIFT descriptor capable of describing the global energy information of the image.We further proposed a spatial SIFT -oriented non-rigid registration model.Experimental results indicated that fast and accurate registration could be achieved with this method.
