Abstract: A new fusion method of multi-focus images based on the nonsubsampled three-channels non-separable wavelets is proposed to improve the inadequate existing in the separable wavelets fusion method. A non-separable wavelet 4-channels filter bank using the theory of non-separable wavelets is constructed and applied in the experiments. The experimental results show that it has good effect for the fusion of multi-focus images. The performance of the non-separable wavelet fusion method is better than the performance of the separable wavelet fusion method.
