| 摘 要： | 针对IHS变换融合影像时存在较严重的光谱失真现象,利用主成分变换对IHS变换法进行了改进.新方法首先对多光谱影像做IHS变换得到亮度I,色度H,饱和度S三个分量,然后用I分量和高分辨率全色影像做主成分变换,并提取第一主分量,并以I为标准进行直方图匹配;将匹配后的影像与H,S进行IHS反变换得到新的多光谱图像.主观视觉分析和客观参数表明,该方法不仅很好的保留了影像的光谱信息,而且兼顾了地物细节能力的表达.

| Abstract: | In view of the spectrum distortion of IHS transformin,an improved remote sensing image fusion method is presented based on IHS transforming and Principal Component Analysis(PCA) Transforming.Firstly,the multi-spectral image is transformed by IHS transform,and I,H,S components are obtained;Secondly,the panchromatic image and I component are merged with PCA transforming.And the first component is obtained and the histogram of the first component is matched according to I.and I was replaced by the matched data... |
