Fusion of Multispectral Bands and Panchromatic Band of ETM Images Based on the Combination of Wavelet Transformation and IHS Transformation

The fusion of images of remote sensing not only improves the resolution of image, but also preserves the multispectral features. A method, which is the combination of wavelet transformation and IHS transformation, is described in this paper. The fusion of multispectral bands and panchromatic band of ETM images is achieved by using this method. The result of the fusion indicates that the method of combination of wavelet transformation and IHS transformation is more advanced than the method of IHS transformation in the fusion of multispectral bands and panchromatic band of ETM images.
