高空间分辨率遥感影像融合方法探讨

raditional fusion methods can obtain good results in combining panchromatic(PAN) and multispectral (MS) images of low spatial resolution. However, this methods can not perform well in high resolution images, as their panchromatic range have border form visible bands to near-infrared bands. This paper is contraposing the characteristics of high spatial resolution remote sensing images. The author did images fusion experiments using the methods of IHS, Brovey, PCA, Gram_Schmidt and Pansharp and made scientific comparisons of the visual effects, spectrum sections and quantitative analysis. The conclusion is that Pansharp and Gram_Schmidt algorithm are more suit for the fusion of high spatial resolution remote sensing satellites.
