In order to solve the problems that the image fusion method based on separable discrete wavelet transform has block effect in the fused image and the spatial resolution is lower in the fusion result image of nonsubsampled non-separable wavelet transform

a new multispectral image fusion method based on sampled two channel non-separable wavelets is proposed.The filter banks relating to this kind ofwavelet are constructed.The multi-resolution decompositions of the intensity of the multispectral image and panchromatic image are performed in sampled mode using the constructed filter bank.The low frequency and high frequency coefficients are fused by different fusion rules.The experiment results show that this method has good visual effect.The fusion performance outperforms the IHS fusion method

the fusion method based on DWT

IHS-DWT

IHS-Contourlet transform

IHS-Curvelet transform and SRF in preserving spectral quality and high spatial resolution information.When compared with the fusion method based on nonsubsampled two-channel non-separable wavelet

the proposed method has been observed to have higher spatial resolution and good global spectral information.
