摘　　要：本文提出了采用光顺–变形–映射–修正四个步骤来解决特征复制的问题,先给出了离散曲线的Gauss光顺算法,再通过曲线演化算法实现了多线外形的变形,然后建立两个多线外形间的映射得到特征曲线网,最后对特征曲线网进行局部修正。本文在自主设计的图形图像处理软件DateSet上验证了算法正确性,该方法适用范围广,解决了快速、准确地实现特征曲线网复制的问题。This paper is put forward to use smooth-deformation-mapping-fixed four steps to solve the problem of feature replication. First, it gives the Gauss smoothing algorithm of discrete curve. Then, it realizes the deformation of multi-line shape by the curve evolution algorithm. Next, it establishes a map-ping between two multi-line shapes to get the feature curve network. Finally, it fixes the feature curve network locally. The paper verifies the correctness of the algorithm on DateSet, which is a self- designed graphic and image processing software. This algorithm has a wide range of application and solves the problem of realizing the replication of the feature curve network rapidly and accurately.
