An Image Fusion Algorithm Based on Lifting Wavelet Transform and IHS Transform
一种基于提升小波变换和IHS变换的图像融合方法

In order to fuse a high-resolution panchromatic image and a low-resolution image effectively, a novel image fusion algorithm using lifting wavelet transform and the IHS transform is proposed in this paper. The high-resolution panchromatic image is firstly decomposed by lifting wavelet decomposition without down-sampling to the lifting wavelet planes. Then the region is divided by edge information from the lifting wavelet planes and the proposed merging algorithm is done by adding edge influence factor in different regions. At the same time, the region is divided based on the evolutionary alogrithm. The method proposed is compared with the IHS, the wavelet transform and other improved methods. The results of the comparison demonstrate that the proposed algorithm can fuse images with high quality more effectively for the test images.
