Digital Image Matching Method Based on Multi-Measure

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.
