Abstract

Aimed at solve the spectrum distortion problem of the IHS method that exists in the QuickBird data

fusion, this paper proposes the utilization of both the visual-pan band method and the linear weighted matching

method for its improvement, and provides the best value range of the coefficient α in the Visual-Pan band method

as well as the best weighted values of Pan and I when the spatial characteristics and the spectral characteristics

of the linear weighted matching fusion image achieve the best result. Tests show that when the value of α is

between 0.2 and 0.25, satisfying fusion effect can be obtained, and when the weighted values of Pan and I are 3/4

and 1/4, the spatial characteristics and the spectral characteristics of fusion image can achieve the best result.
