Firstly,grey absolute correlation degree is used to discriminate non-edge pixels and edge pixels in high resolution images,by which the weight of intensity component is identified in order to combine it with high resolution image.
鉴于IHS变换的融合影像存在光谱扭曲问题,而灰色关联度对图像边缘检测具有局限性,该文将基于灰色绝对关联度的灰色关联分析与IHS变换相结合进行影像融合。
