Abstract

Abstract: Using the wavelet transform and the fusion rule based on windows for choosing the largest coefficient absolute sum，the multi-focus images will be susceptible to noise and have incomplete fusion information.This paper presents a kind of fusion rule which will select the coefficients of two images for the fusion to make the fusion images contain the information of original images as much as possible.Comparison of fusion results of multi-focus image is given.The proposed fusion rules can achieve better fusion performance than other usual fusion rules，avoiding losing information.

Key words: wavelet transform, fusion rules, image fusion

摘要： 针对多聚焦图像，通过小波变换和基于窗口的系数绝对值和选大融合规则，存在着对噪声敏感和融合信息不完整等缺点。为了克服这些缺点，使融合后的图像包含尽可能多的源图信息，提出了一种在融合时两幅图像的系数都选取的融合规则。通过对多聚焦图像融合的实验结果比较表明，提出的融合规则的融合效果更优，可避免信息损失。
