| A Non-rigid Registration Algorithm Based On Fast Optimization Image Edge Pyramid Abstract Pyramid structure search algorithms used in rigid registrations have an unlimited starting point and search range. The improved LOG operator will be used to extract the edge image and construct an edge pyramid image suitable for non-rigid registration. Based on the improved Powell method, a fast image non-rigid matching algorithm is constructed. First, low-resolution edge images are matched, and then the full-resolution image matching can be gradually realized. Experimental results show that the algorithm can effectively reduce the computational load and improve the efficiency remarkably.
