A new fusion method of multispectral and panchromatic image based on NSCT and HIS transform

A new multi spectral and panchromatic image fusion, which is based on Nonsubsampled Contourlet Transform (NSCT) and HIS transform, is proposed in this paper. First, I component was obtained from multispectral image through HIS transform. Second, NewI coefficients were gained by fusion algorithm, which performed on I component and Panchromatic image by NSCT transform. Finally, the fusion images were received by inverse HIS transform on H and S component of multispectral image and NewI. The experiment results show that the proposed algorithm not only preserves spectral information of original images well, but also enhances detail texture information in image fusion.
