A new multispectral image fusion method based on intensity-hue-saturation (IHS) transform and three-channel non-separable wavelets whose dilation matrix is [2,1;–1,1] is proposed. The multi-resolution decompositions of the intensity of multispectral image and panchromatic image are performed in nonsubsampled mode using the three-channel non-separable wavelet filter bank. The approximation images and the detail images of the multi-resolution pyramids are fused. The experimental results show that
