Effective Recognition Algorithm for Digits Based on Combination Features
基于组合特征的高效数字识别算法*

An effective recognition algorithm is proposed for digits on monitor screen.By using the features of euler number,concave field,horizontal and vertical crossing Line,digits can be classified and recognized.The algorithm doesn't needs any regularization,thinning and outlining operations on the digits image.So it achieves low memory and computation.With the proposed method a monitor information catching and record system is realized.More than 5000 digits are involved in the expe-(riments) and a conclusion is drawn that the average recognition rate is 98.70%,the error rate is 1.30%,and the recognition speed is 125 digits per second.Experiments show that the algorithm is fast with high recognition rate and strong anti-interfe-(rence) ability.
