| 摘 要： | 针对多光谱图像与全色图像的融合,本文提出了一种基于IHS变换和形态小波变换的遥感图像融合方法。新方法首先对多光谱图像作IHS变换,得到亮度I,色度H,饱和度S三个分量;其次,利用形态小波变换融合方法融合多光谱图像的亮度分量与全色图像,并用融合后的图像代替多光谱图像的亮度分量;最后,作IHS反变换得到新的多光谱图像。主观视觉效果分析和客观统计参数分析评价分析表明,新方法的性能优于IHS变换融合、小波变换融合方法,不仅较大地增强了融合图像的空间细节表现能力,而且很好地保留了多光谱图像的光谱信息。

| Abstract: | This paper presents a new remote-sensing image fusion method based on IHST and MWT to address the fusion of multi-spectral images and panchromatic images.Firstly,multi-spectral images are transformed by IHST to obtain I,H and S components;secondly,panchromatic images and the I-components of the multi-spectral images are merged with the MWT-based fusion method,and then the I-component is replaced by the merged data;finally,fused images are obtained by inverse IHST.Visual results and statistical parameters indicate that the performance of the new method is superior to that of the IHST-based,WT-based methods.It considerably enhances the spatial detail information of fused images and preserves the spectral information of the original multi-spectral images to a large extent. |
