Abstract :
An accurate method for recognition of printed Chinese characters is proposed. An improved peripheral method and the Walsh transform of both horizontal and vertical projection functions of a Chinese character are used for feature extraction. Study shows that this method has the advantages of fast processing speed, accurate recognition rate, and strong resistance to noise
