提出了一种新的基于小波变换的多光谱与高分辨率图像融合方法 该方法通过强度因子有效地将高分辨率图像经小波分解的低频分量信息融合到多光谱图像经小波分解的低频分量中去 ,使得经过小波反变换的融合图像较大程度地保留了多光谱图像的光谱信息和高分辨率图像的空间分辨率 给出了该方法的融合结果 ,并与小波变换法 (WT方法 )进行了比较 ,证明了该图像融合方法的正确和有效性 A new fusion method of multi-spectral and high-resolution images based on wavelet transform is proposed. The proposed method combines the low-frequency components of high-resolution image by wavelet transform into the low-frequency components of multi-spectral image through wavelet transform So that the fused image which is inverse transformed by wavelet transform retains the spectral information of multi-spectral image and the spatial resolution of high-resolution image to a great extent, and presents the fusion result with wavelet transform method (WT method) The comparison shows that the image fusion method is correct and effective
