IHS method for image fusion is one of the conventional methods with a simple theory. Implementation of this method is simple and effective from computational point of view. But this method causes the spectral content of the fused image to get disturbed in comparison with the spectral criteria of the main multispectral image. In this article a statistical image fusion method is combined with the conventional IHS method to improve its spectral quality and overcome its deficiency. Some spectral indices were used for evaluation of this combined method and compared with the conventional IHS and the used statistical fusion methods. This combined method improves the spectral quality of the fused image and eliminates the existing shortcomings of the spectral disturbing in fused image produced by IHS method.
