A new algorithm of image fusion
一种图像融合新算法

A new algorithm is developed to merge a high-resolution panchromatic image and a low-resolution multi-spectral image based on the combination of multi-resolution wavelet decomposition, evolutionary strategy and the IHS transform. The high-resolution panchromatic image is firstly decomposed to the wavelet planes, then the region is divided by the wavelet planes and the proposed merging algorithm is done by adding edge influence factor in different region. The proposed method is compared with the IHS and the MWD methods. The results of the comparison show the proposed merger performing the best in combining and preserving spectral-spatial information for the test images.
