Image Registration of CT and DR Based on Improved SUSAN

Abstract:

The paper completes image registration of medical CT and DR through improved SUSAN algorithm. First, the paper divides the image into a certain number of anatomical point regions with some significance, and sets different grayscale D-value for different regions to make corners distribute equably. Second, the paper uses the size of the USAN from limited corner regions to reduce the number of corners and the computation. Then the paper adopts confidence algorithm, find the correct match points by setting threshold, and thus completes image registration.
