多聚焦图像融合中小波基函数选取的研究

Study on the Selection of Wavelet Base for Muti-focus Image Fusion

在基于小波变换的多聚焦图像融合算法中,小波基的选取是一个问题。分别从基于像素的融合算法和基于区域的融合算法两个方面,选取不同的小波基,做了大量的实验。考虑到评价参量的典型性和算法的复杂度,选取熵、均值、标准差、可见度,平均交叉熵5个参量对实验结果进行评价分析。

In the multi-focus image fusion based on wavelet transform , the choice of wavelet base is a question. I did a lot of experiments in two methods based on pixel and based on region, using many different wavelet bases. The representative and complexity of estimate standard is thought about, I chose entropy, average value, standard error, visibility and mean-cross entropy to evaluate the result of the experiments.
