Research and implementation of Manchu character recognitionpost processing based on statistics

ZHAO Ji~1,WANG Li-jun~1,LI Jing-jiao~2(1.School of Computer Science and Engineering,Anshan University of Science and Technology,Anshan 114044,China;2.School of Information Science and Engineering,Northeast University,Shengyang 110004,China)  
So far,it is not possible that the rate of single character recognition(SCR) reach 100%,as a rusult,the SCR system can produce inaccurate and rejective judgement.So an information database of Manchu phrases and undetermined words were constructed by combining the recognition information of Manchu word recognition system and Manchu phrase information.The method of hidden Markov model based on statistics was adopted,and the optimized path was figured out by using Viterbi dynamic programming method,which would be used for postprocessing of Manchu character recognition.This means can effectively improve the recognition rate of the system.The experiment indicates that the higher the recognition rate of SCR,the better result of postprocessing.
