摘　　要：提出了一种多光谱与高分辨率图像融合的新算法 .该方法将小波的多分辨分解与IHS变换相结合 ,它首先利用高分辨率图像各小波面叠加的边缘信息进行区域划分 ,再通过融合算子实现分区域融合 ,最后对融合后的强度分量进行IHS反变换 ,得到一幅同时具有较好空间分辨率和光谱信息的融合图像 .实验结果表明 ,该方法得到的融合图像优于IHS变换法和小波变换法 (WT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 and the IHS transform. The high-resolution panchromatic image is firstly decomposed to the wavelet planes, then the region is divided by edge information from the wavelet planes and the intensity component from multi-spectral image is merged by fusion operator in different region. The proposed method is compared with the IHS and the WT methods. The experimental results show that the proposed method can achieve better fusion performance in combining and preserving spectral-spatial information.
