Printed Chinese character recognition is an important subject of Chinese information processing. Because there are different kinds disturbances,preprocessing must be carried out before a Chinese character image can be recognized.We present a preprocessing method,which includes binary processing,smoo thprocessing,line segmentation,character segmentation and normalization. In the key step of binary processing,we propose a threshold-selecting method.First,we work out the gray statistical histogram of the Chinese character image,then smooth the histogram repeatedly by using the weighted near neighbor points until two global peak points are obtained. Find the lowest point of the two peak points and take it as the threshold of the Chinese character image;We used this preprocessing method in printed Chinese character recognition in which neural network technology is used,and got a satisfactory result.
