In this paper, we propose an image fusion method based on the non-separable wavelet frame (NDWF) for merging a high-resolution panchromatic image and a low-resolution multispectral image. The low-frequency part of the panchromatic image is directly substituted by multispectral image. As a result, the multispectral information of the multispectral image can be preserved effectively in the fused image. Due to multiscale method for enhancing the high-frequency parts of the panchromatic image, spatial information of the fused image can be improved. Experimental results indicate that the proposed method outperforms the IHS transform, discrete wavelet transform and separable wavelet frame in preserving spectral and spatial information.
