【Abstract】 A robust image registration algorithm is proposed,which includes the following two stages:①initial matching,SIFT matching method and the normalized cross correlation(NCC) metric modified with adaptive scale and orientation of SIFT features are proposed to find good initial matches,and the geometric consistency check is used to identify false matches;②matching propagation,a robust matching propagation using adaptive NCC and local homography constraint starts from the initial correspondences estab... 更多还原
