摘　　要：提出一种新的由向量字自动生成曲线字的方法,实现思路是对向量字轮廓进行合理的分段,然后对一段连续的向量段用一条直线段或三次Bezier曲线段替换,从而生成曲线字。提出一种先对轮廓线进行插值,再迭代提取关键点,然后去掉冗余关键点的向量字形轮廓分段方法。采用最小二乘法反求Bezier曲线控制点,进行曲线拟合从而生成曲线字形轮廓。结果表明,该方法计算简单,以较少的关键点实现了对向量字轮廓的较好拟合,基本保持了字形特征。A new method for auto-generating curve contour character from vector contour character was proposed. The main idea of the implementation is to segment the vector contour character reasonably and then to replace every continuous vector subsection with a piece of straight line or a Bezier, so the curve contour character will be generated. A new segment method in auto-generating curve contour character was proposed. This new method is as follows： firstly the vector contour is interpolated, then the key point was iteratively searched, and the next step should remove the redundant key point; finally the curve contour character is generated by using the least square method. The result shows that this method is very simple and can make better approach of vector contour character with less critical point, and it also can keep the character of vector contour characters.
