A Fast Recognition System for Paper Currency Numbers
Zhang Yu · Jisuanji gongcheng · 2005
An automatic recognition system for paper currency numbers is developed.The paper currency number is recognized and recorded with binding by the system.Firstly,24 bits color image is gathered through CCD camera,then outputs number clusters through process of segmentation by gray ridge-vale algorithm,orientation by projection,and character recognition by structure-analyzing algorithm.Experimental results demonstrate the proposed algorithm of gray ridge-vale can extract number image effectively,the distance of traversing number body is accuracy,the recognition system achieves a high recognition rate and fast recognition speed.
