A Fusion Method of High-resolution Images Considering Spectral Distortions

The local correlation coefficient is introduced and the different thresholds at different levels of wavelet decomposition are set up, in order to reduce the spectral distortions of the fusion image,fuse multi-spectral images with a panchromatic image of Quickbird data by the proposed method.The result demonstrates that the proposed method is a good fusion method to increase information,improve resolution and reduce spectral distortions.
