摘要
概述了数据融合的基本概念和应用,简明分析了多聚焦图像的成像机理,从像素级层面上描述了基于小波多尺度变换的图像融合思想和过程。由于在基于小波变换的图像融合过程中,融合规则起很重要的作用,因此本文重点综述了适于多聚焦图像融合的三种融合规则:基于像素的融合规则、基于窗口的融合规则和基于区域的融合规则,并对这些规则进行了比较,最后给出了图像融合效果的客观评测方法。
This paper summarizes basis concept of data fusion and its application. The basic principles ot multifocus imaging is analyzed. The methods of image fusion based on wavelet transform and pixels is described. The rules are important to the fusion. Three fusion rules are presented and compared, including pixel - based fusion rules, windows - based fusion rules and region - based fusion rules. The criteria how to evaluate image fusion is given finally.
