Chinese characters stroke thinning and extraction based on mathematical morphology
Guojun Luo · Journal of Hefei University of Technology · 2005
In this paper,a novel method for Chinese characters stroke thinning and extraction based on mathematical morphology is proposed.According to the structure of Chinese characters,a new group of structure element sequences is defined so that the connectivity and topologic features of the skeleton of original Chinese characters can be held,and distortion and deflection of the Chinese characters strokes after sample's thinning can be restrained effectively.Based on this result of Chinese characters stroke thinning,a new algorithm of stroke extraction method for Chinese characters is defined,then the horizontal,vertical,right-diagonal and left-diagonal strokes of original Chinese characters are extracted exactly,and the information of their shape and structure is acquired.
