    • The present invention provides a panchromatic sharpening method of spectral image based on fusion of overall structural information and spatial detail information, comprising: performing brightness linear stretching on a panchromatic image, so as to set the variance of the panchromatic image to be equal to the variance of said spectral image; respectively interpolating N components of the spectral image so as to generate an interpolation image series having the same resolution as that of the panchromatic image; subtracting the interpolation image series from the panchromatic image after said linear stretching to obtain difference images; performing Gauss filtering on the difference images, thereby obtaining difference tendency images; and, respectively subtracting the difference tendency image series from the panchromatic image after said linear stretching, thus obtaining fused images. The method can maintain both spectral fidelity and texture detail fidelity of the fused images, support high computation speed, and has wide applicability.
    • 本发明提供了一种基于整体结构信息和空间细节信息的融合的光谱图像的全色锐化方法,包括:在全色图像上执行亮度线性拉伸,以将全色图像的方差设置为等于方差 的所述光谱图像; 分别内插所述光谱图像的N个分量,以产生具有与全色图像相同分辨率的内插图像序列; 在所述线性拉伸之后从全色图像中减去插值图像序列以获得差分图像; 对差分图像执行高斯滤波,从而获得差异趋势图像; 并且在所述线性拉伸之后分别从全色图像中减去差异趋势图像序列,从而获得融合图像。 该方法可以保持融合图像的光谱保真度和纹理细节保真度,支持高计算速度,具有广泛的适用性。
