The research of printed Chinese characters recognition technology
Abstract: Printed Chinese character recognition technology is a kind of automatic high-speed, information input method, become the important functions of the computer interface, still can as office automation, the press and publishing, machine translation, etc, the ideal input has wide application prospects. The aim of Chinese character recognition is to make the Chinese input more natural and convenient so that the computer could process Chinese information more easily. In practice, large volume of letters, newspaper, magazines need to be covered into a coded representation of the input characters. That's what printed Chinese character recognition can do. Firstly, in chapter 1，this thesis gives what is the significance of research and background of Chinese character recognition and introduce the problems we encountered now. The chapter 2，it is a basic overview of the recognition process of printed Chinese characters. In chapter 3, we discusses the principles and printed character recognition, feature extraction and analysis, the post-processing process, Emphatically analyses the statistical pattern recognition method, structural pattern recognition method and Artificial neural network pattern recognition method. In chapter 4, giving an Matlab simulation concludes the whole article and forecast characters identification technology research directions of future development.
