Recognition Techniques of Off-line Hand-printed Chinese Characters
Changhui Liu · 2000
Based on the relaxation matching method, this paper gives a algorithm of tracing the contour and selecting the turning points by using the distances between points on the contour of Chinese characters, therefore, the speed of extracting the turning strokes is greatly improved. According to the out-contour turning strokes of Chinese characters, the matching is classified three levels, and then the relaxation matching in full domain is changed into partial domain relaxation matching, which is called dynamicsequential-flexible matching approach. As a result, the matching speed is raised efficiently. In the first level classification, we adopt several models, and increase efficiently the correction rate of classifying by the positions of radicals. At last, the off-line hand-printed Chinese characters are recognized by using the intercontour turning strokes.
