提出了一种基于小波变换的高分辨率全色图像与低分辨率多光谱图像融合方法。该方法首先利用边缘强度因子将高分辨率全色图像的近似值融合到多光谱图像的近似值中，然后利用融合后的近似值和高分辨率全色图像的细节信息，通过逆小波变换重构融合后的图像。与传统的小波融合方法的比较表明，该方法在融合和保留测试图像的光谱-空间信息方面具有更好的性能。
A new method is presented based on wavelet transform (WT) for the fusion of a high-resolution panchromatic image and a low-resolution multi-spectral image. The high-resolution panchromatic image approximation can be first merged into the multi-spectral image approximation by edge intensity factor, and then the merged image is reconstructed by means of an inverse WT using the fused approximation and the details from the high-resolution panchromatic image. A comparison of the proposed method with old wavelet merging method shows that the proposed method can achieve better performance in combining and preserving spectral-spatial information for the test images.
