Multispectral image fusion method based on intensity-hue-saturation and nonsubsampled three-channels non-separable wavelets

A new multispectral image fusion method based on intensity-hue-saturation(IHS) transform and threechannel 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 this method has good visual effect.The performance outperforms the IHS fusion method.the discrete wavelet transform (DWT) fusion method,and the IHS-DWT fusion method in preserving spectral quality and high spatial resolution information.
