A novel algorithm for the image registration between synthetic aperture radar(SAR)image and optical image is proposed.With this approach,the accuracy of registration won't be affected by speckle noises or the result of feature extraction.Under the level set framework,an energy function is defined with the matching function between two images,and the function can be solved by curve evolution.The efficiency of the algorithm is verified by the real SAR images and optical images of two different scenes.Experimental results reveal that the registrations between multi-sensors are efficient in both high and low SNR images.
