A Hybrid Statistical IHS Image Fusion Method

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