摘要
采用小波变换和IHS结合的方法实现了ETM多光谱波段和ETM全色波段的融合,并与传统的IHS融合的结果进行比较,结果表明小波和IHS变换相结合的方法优于IHS方法。
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 muhispectral bands and panchromatic band of ETM images.
