Feature point method of Chinese character recognition and its application


A new method for recognizing Chinese characters is proposed. It is based on the so- called feature points of Chinese characters. The feature points we use include those on the stroke of a character, i.e., end points, turning points, fork points and cross points, and the key points on the background of character. This method differs from the previous ones for it combines the feature points on stroke with those on back-ground and it uses feature points to recognize Chinese characters directly. A Chinese character recognition system based on top- down dynamical matching of feature point is developed. The system can recognize not only 6763 printed sample Song font Chinese characters of size 5.6×5.6mm2 with high recognition rate, but also the general printed books, magazines and documents with a satisfactory recognition rate and speed.
