Abstract
Optical and SAR images have different imaging modes and pixel expression formats, which caused much difficult for image registration. The paper proposes a registration algorithm combined Ratio gradient and Cross Cumulative Residual Entropy (CCRE) aimed at solving the problem of SAR image speckles. Compared with other traditional methods, the experiment results show that the CCRE combined with Ratio operator registration method performs satisfactorily in SAR and optical image registration and provides a significant improvement on the registration accuracy over the other algorithm
