An approach of remote sensing images registration by using a new feature-based technique

With an increasing number of images collected every day from different sensors, automated registration of multisensor/ multi-spectral images has become an important issue. Image registration is a very important precondition of image fusion. A wide range of registration techniques exists for different types of applications and data sources, however no algorithm is known that can accurately register multi-source images consistently. A new method of remote sensing images registration is presented in this paper. The development of this new automatic image registration method is based on Fourier transform and mutual information, which use wavelet decomposition technique. The result of experiment shows that this algorithm can effectively solve the image registration of remote sensing images with quite different diversities, and it has a high value in use.
