Abstract

The fusion of panchromatic image and multispectral image is one of the significant issues in the application of remote sensing , by which it can integrate multispectral and panchromatic images with their respective strengths to compress the data size and improve data utilization. In this paper, an IHS (Intensity-Hue-Saturation) image fusion method is presented based on Bidimensional Empirical Mode Decomposition (BEMD).Firstly, multispectral image is transformed form the RGB color space to HIS color space, then I component and panchromatic image are carried out decomposition respectively using BEMD method. The intrinsic mode surface of decomposed panchromatic image is used to replace that of decomposed I component. Finally the image is transformed back to original RGB color space from IHS color space, achieving the image fusion. The experiment shows that the new image fusion method is superior to the traditional methods.
