  • This paper researches the multiscal geometry analysis tool, NonSubsampled Contourlet Transform (NSCT), and proposes a new method of fusing panchromatic and multispectral images based on NSCT and Stationary Wavelet Transform (SWT). This method first performs NSCT on panchromatic image and the intensity component of multispectral image with IHS, then fuses the low frequency coefficients with SWT for further spatial information extraction, and fuses the high frequency coefficients based on local average gradient fusion rule, finally a fused image is obtained through inversing NSCT. The experimental results show that the proposed method can effectively preserve spectral information and improve spatial information of the fused image, and outperforms the traditional IHS, wavelet, DT-CWT and contourlet methods.
