Aiming at the problem that how to improve the accuracy and speed of image registration,this paper presents a pyramid approach for image registration based on mutual information and Fourier-Mellin,which integrate the accuracy of calculating linear parameters in Fourier-Mellin-based method and the accuracy of calculating rotation and scale parameters in mutual-information-based method.Experimental results on remote sensing images demonstrate the presented method can decrease the registration time and improve the accuracy.
