摘要
通过研究相关函数、协方差函数、相关系数、差平方和、差绝对值和、互信息等六种测度的匹配效果,比较六种测度的优缺点,选取匹配效率高、可靠性强的匹配方法。同时,为了提高匹配可靠性,本文探索了一种基于相关系数和互信息的联合匹配测度。
Through the study of matching effect of six measures containing correlation function,covariance function,correlation coefficient,sum of difference squares,sum of difference absolute values,and mutual information,this paper compares the advantages and shortcomings of the above six measures,and chooses matching method of high matching rate and reliability.In the meantime,in order to improve matching reliability,this paper explores a joint matching measure based on correlation coefficient and mutual information.
