小波变换和梯度对多聚焦图像的多分辨率融合

Multi-Resolution Fusion of Multi-Focus Image Using Wavelet Transform and Gradient

提出一种结合Roberts梯度和小波变换的图像融合方法。该方法对低频分量采用加权平均,对高频分量采用结合梯度平均值的规则。实验结果表明,该方法能够提高多分辨率图像融合方法的效果。

The paper develops an image fusion algorithm based on Roberts gradient and multi-resolution.The fused approximate coefficients are obtained by average method,and the fused detailed coefficients are obtained by average of gradient.Experimental results show that the proposed algorithm could improve the quality of multi-resolution image fusion.
