| 摘 要： | 应用CHIS(Generalized-Hue-Intensity-Saturation)变换融合多光谱影像与全色影像中存在的光谱扭曲问题,主要是由于变换后的I分量与全色影像之间差异过大.为此,本文提出了一种基于统计关系定权的I分量计算方法,从数据整体角度考虑,在不能获取I分量与多光谱影像准确函数关系情况下,通过各波段影...

| Abstract: | The reasons that causes spectral distortion in various HIS transform methods in the fusion of multi-spectral images and panchromatic image are the differences between I component and panchromatic image.A method was proposed to calculate I component using the weights decided by correlation coefficients between multi-spectral images and panchromatic image in the case of no exact functional relation,and made I component as closely to panchromatic image.Two different data sets were used to evaluate the proposed... |
