摘要
本文给出了数字图象边界的多边形逼进的算法和步骤，讨论了边界噪声的去除，边界形状控制点的获取，提出了改进运算速度的递推算法以及保持尖点不变的拟合原理．
An algorithm about polygonal approximation to the boundary ofdigital image based on fixed shape are given in this paper. The methods for removing noise of boundary and finding dominant points at boundary are discussed.A recurrent algorithm to improve the speed of calculation is developed.The principle of fitting the boundary with sharp venices is put forward.
