摘　　要：针对可分小波多聚焦图像融合方法存在的不足,提出了一种基于非下采样三通道不可分小波的融合方法。根据不可分小波理论,构造了一组3通道4×4的不可分小波滤波器组,并把此滤波器组应用于多聚焦图像融合中。实验结果表明,该方法对多聚焦图像的融合有较好的融合效果,其融合性能好于采用相同融合算法的基于张量积小波的融合方法。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 experi- ments. 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.
