Fusion of High_resolution Panchromatic and Multispectral Images by Using Wavelet Transform
小波变换用于高分辨率全色影像与多光谱影像的融合研究

This paper presents a new image fusion scheme based on the combination of multi_resolution wavelet decomposition and IHS transform for the fusion of High_resolution Panchromatic and Multi_spectral images. The Panch romatic high resolution image is firstly decomposed to the wavelet planes, then the wavelet planes are added to the intensity component of IHS representation of th e multi_spectral image. In the proposed method all the spectral characteristics have been preserved, and the definition and the spatial quality of multi_spectra l image have been improved. Fusion result keeps the contrast of multi_spectral i mage. Experimental results including the fusion of black_white aerial and Landsa t (TM) images, Landsat TM and SAR images are presented. Compared with the WT and IHS method, the proposed scheme is much better and it possesses more adaptabili ty.
