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
武汉测绘科技大学测绘遥感信息工程国家重点实验室,武汉430070
摘要:

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。

Fusion of High_resolution Panchromatic and Multispectral Images by Using Wavelet Transform
Abstract:

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.
