Image is decomposed in the first step of the wavelet transformation fusion. And then each level component is analyzed for obtaining the most related image level, and at last, the images based on wavelet direction contrast gradient are fusion.
基于小波变换的融合方法的主要步骤是,先分解图像,分析各个层次图像的相关关系,确定最优的分解层次,依据小波方向对比度融合规则融合图像,经过仿真实验证明在层次融合选取上本方法更科学,得到的融合图像的边缘更清晰。
