基于Hausdorff距离的轮廓线匹配

Contour matching based on Hausdorff distance

提出了一种轮廓线的匹配方法。首先,通过计算轮廓上每一点的曲率并选取特征点,以特征点及其两侧的若干点构成特征段,用特征段对轮廓进行分段描述,然后用特征段之间曲率的Hausdorff距离来度量分段轮廓之间的相似性,获得匹配结果。实验证明该方法是有效的。

A method of matching contours is introduced in this paper. The main idea was firstly to calculate curvature of the contour, and then the feature points were selected, several feature segments that consist of the feature point and some points in it＇s neighborhood depict a contour. The comparability of segments is measured by Hausdorff distance. The method proves to be effective by realistic experiments.
