将小波的多分辨率分析与ＩＨＳ变换相结合，提出了叠加融合的新方法。它先对高分辨率影像进行小波分解，得到的各小波面叠加到多光谱影像经ＩＨＳ变换后的强度Ｉ影像中，使得融合影像最大限度地保留了多光谱影像的光谱信息，保持了原多光谱影像的反差，同时提高了它的清晰度和空间分辨率。文中给出了黑白航空影像与ＴＭ影像，ＳＡＲ影像与ＴＭ影像的融合结果，并与ＷＴ法、ＩＨＳ法进行了比较，证明了本方法的优越性和自适应能力 Combining the multiresolution analysis of wavelet and IHS transform, a new method of superposition fusion is proposed. Firstly, the wavelet decomposition of the high resolution image is carried out, and each wavelet surface is added to the intensity I image of the multispectral image transformed by the IHS, so that the fused image retains the spectral information of the multispectral image to the maximum, Spectral image contrast, while improving its clarity and spatial resolution. The paper presents the fusion results of black-and-white aerial images and TM images, SAR images and TM images. Compared with WT and IHS methods, the method proves the superiority and adaptability of this method
