A new algorithm for fusing thé high-resolution pan with
multi-spectral low-resolution image was developed. The
method is base on a atmospheric correction with constructing a
new PSF matrix and spectral simulation with multi-spectral
bands. There is an obvious improvement in pan-sharpness and
extracting geographic features, especially in analyze the tiny
objects and texture. It is concluded that the new
pan-sharpening algorithms is a perfect algorithm in fusing the
high-resolution pan with ms low-resolution image in RS data
fusion.
