The structural features of Chinese character are suitable for the recognition process of handprinted Chinese character because of the advantage of high tolerances to distortions and style variations. The extraction of the stroke feature is very difficult. Wavelet transformation which is a powerful tool in image analysis is used to analyze the Chinese character image in this paper, and then the process of the extraction stroke is concise and distinct.
