提出了一种毛笔字功能字形自动生成系统。该系统提取边界线的尖角（所谓的关节点），并使用分段多项式近似相邻关节点之间的边界线。所生成的函数字体的质量由接合点的位置控制。尝试开发一种先进的功能字体生成系统，并提出了提取适当关节点的算法。该算法包括三个阶段：（1）通过估计数字曲率提取关节点，（2）通过估计近似边界线的曲率提取附加关节点，（3）去除冗余关节点。通过对毛笔字、印刷体字和数字的识别，验证了该方法的有效性。<<ETX>>
An automatic function-font generating system for brush-written characters has been proposed. The system extracts sharp corners of boundary lines, (so-called joint points), and approximates the boundary lines between adjacent joint points using a piecewise polynomial. The quality of the generated function-fonts is controlled by the location of joint points. An attempt is made to develop an advanced function-font generating system with an algorithm to extract appropriate joint points. The algorithm consists of three stages: (1) extracting joint points by evaluating digital curvature, (2) extracting additional joint points by evaluating the curvature of approximated boundary line, and (3) removing the redundant joint points. The performance of the method is verified by applying it to brush-written characters, printed characters, and figures.<<ETX>>
