This paper discusses the method of denomination identifying for current RMB banknotes by means of image processing.The approach of template matching is applied according to only few kinds of (current) RMB banknotes being current.Although the traditional method of two-dimensional template (matching) can be achieved simply,but the calculating quantities are much larger,it may take very long time.Under this circumstance,algorithm of template matching based on one-dimensional gray projection is (adopted).Using this algorithm we get one-dimensional image through gray projection,then use this one-(dimensional) image to achieve quick match.The result of experiments indicates that the latter method can keep higher matching precision,meanwhile the recognition speed is obviously higher than the former.Consequently,the equipment′s speed of recognition is greatly increased,which make it have more practicalities.
