In order to further improve the effect of image fusion and the performance of fusion algorithm and on the basis of the in-depth analysis of various different image fusion strategies, this paper has proposed a multi-resolution neighborhood energy contract fusion algorithm based on wavelet analysis.This method can better abstract the important features and detail information of the source image and improve the information entropy reflecting the information richness, the average gradient of the image details and marginal information as well as the overall activity level of the image compared with other fusion methods. More over, it has better evaluation parameters than other fusion methods, suggesting that this method is effective in multi-focus image fusion and that it can achieve good effects.
