基于区域能量特征的小波变换图像融合方法研究

Research on Image Fusion Based on Wavelet Transform and Region Energy Rules

本文提出了一种新的基于区域能量特征的小波变换图像融合方法,在对高频部分进行融合前,先将高频信息进行适当的放大,然后再采用基于区域能量特征的图像融合方法。通过仿真实验表明,该融合方法弥补了传统的基于区域能量特征的小波变换融合中出现的信息熵减小,清晰度降低的现象,验证了该方法的有效性。

This paper present a new image fusion method based on wavelet transform and region energy rules.For the high-frequency image of wavelet decomposition,we should expand them by proper proportion,and then fusion them by region energy rules.Experiments shows that this method can cut down influence of the decreases of information entropy and reduce of clarity appear in traditional methods.This method is feasible and effective.
