摘要
针对传统的AIHS变换融合算法频谱失真问题,提出了一种改进的AIHS变换方法。该方法用多光谱影像边缘加权矩阵代替原有全色影像边缘加权矩阵,将全色图像加权矩阵与多光谱图像加权矩阵进行线性组合得到新的加权矩阵,进而决定全色图像注入到多光谱图像每个频带的空间细节量,从而得到IAIHS变换的定义式,即全色图像第i个频带与空间细节量的线性组合。实验结果表明,与传统AIHS变换方法相比,IAIHS变换方法可以很好地保持光谱质量。
Aiming at the problem of spectral distortion of traditional AIHS transform fusion algorithm,an improved AIHS transform method is proposed. In this method,the multi-spectral image edge weighting matrix is used to replace the original full-color image edge weighting matrix,and the panchromatic image weighting matrix is combined with the multi-spectral image weighting matrix to obtain a new weighted matrix,which determines the amount of detail when the full color image is injected into the multi-spectral image. Then the definition of IAIHS transformation is obtained,that is the linear combination of the full-color image i-band and space detail. The experimental results show that the IAIHS transform method can maintain the spectral quality well compared with the traditional AIHS transformation method.
