| 摘 要： | 为了对联机手写字符识别的笔画进行精确描述,提出了一种基于字符笔画特征抽取的＂逼近-合并＂算法.该算法分析了字符笔画的多边形逼近,求出偏离度最小的多边形逼近,并对该多边形的边进行合并,抽取出笔画方向码,实现了联机手写字符笔画的更有效合并.该方法应用在联机手写体字符识别实验系统中,其识别率为99.13%.

| Abstract: | An approximation-integrate method of extracting stroke features is presented for exactly describing strokes of online handwritten characters. The polygon approximation for character strokes is analyzed, the minimum deviation polygon approximation is founded. The strokes are integrated and the strokes codes are extracted. The integration of online handwritten character strokes is realized more efficiently. This method has been applied in the experimental system of handwritten character recognition. The test result shows that the recognition rate is 99.13 %. |
