Abstract
Multi-spectral Image Fusion is a new research field in image processing. In this paper, for achieving a better fusion result, a image fusion method based on the intensity-hue-saturation(IHS) Transform and Bidimensional Empirical Mode Decomposition(BEMD) is proposed. Firstly, the multi-spectral image is transformed into IHS component. Secondly, the histogram-matched panchromatic image and intensity component are decomposed into a set of BIMFs respectively by means of BEMD. Thirdly, the new intensity component can be obtained by merging the BIMFs of histogram-matched panchromatic image and intensity component. Finally, the new intensity, hue, and saturation components are transformed back to RGB. Experimental results show that this new method can preserve the spectral information in the fusion image; meanwhile, it can merge the spatial details of the panchromatic image.
