一种改进的汉字骨架提取算法

为了更有效地提取汉字的骨架,提出一种基于内切圆提取汉字骨架的新方法。该方法首先对Windows系统中的汉字进行边缘检测,提取出汉字的边缘,然后迭代计算特定步长范围内的内切圆,将各内切圆的圆心连接起来得到书法汉字的骨架。实验结果表明,该方法在提取书法汉字骨架的同时保留了原始汉字的边缘信息,提取的骨架具有良好的对称性和连通性。

An improved algorithm for extracting the skeletons of the Chinese calligraphy

To extract the skeletons of the Chinese calligraphy more effect, a new algorithm of extracting the skeletons of Chinese calligraphy which based on the inscribed circle is presented. In the algorithm, firstly, detect the edge of the character, get the edge of the character, then calculate inscribed circle within the specific step iteratively, get the skeleton of the character after connecting every center of the inscribed circle. The present results show that the algorithm of extracting the skeletons of Chinese calligraphy contain the original skeleton of the characters＇ edge information, and the skeletons produced by this algorithm have good symmetry and connectedness.
