摘要
引进了一种构造曲线的逼近技术 ,它放松了曲线应包含所有数据点这一严格要求 .为了度量一曲线能逼近已给数据多边形的好坏 。
The approximation technique is introduced to censtrut a cure by relaxing the strict requirement that the curve must contain all data points.To measure how well a curve can approximate the given date polygon,the concept of Moving control points is used.
