An improved adaptive intensity-hue-saturation (IHS) method is proposed for image fusion in this paper based on the adaptive IHS (AIHS) method and its improved method(IAIHS). Through improved method, the weighting matrix, which decides how many spatial details in the panchromatic (Pan) image should be injected into the multispectral (MS) image, is defined on the basis of the linear relationship of the edges of Pan and MS image. At the same time, a modulation parameter t is used to balance the spatial resolution and spectral resolution of the fusion image. Experiments showed that the improved method can improve spectral quality and maintain spatial resolution compared with the AIHS and IAIHS methods.
