Research on the Algorithm for Matching 2D Contours
Liyan Zhang · Jiangsu Machine Building & Automation · 2005
A method of matching contours is introduced in this paper, it is a further extension of comparability measure based on Hausdorff distance which is usually used between different images. Several feature segments that consist of the feature point and some points in its neighborhood depict a contour. The comparability of segments is measured by Hausdorff distance. In this way, we obtain the matching fragments. For geometrical characters of the contour itself have been taken good advantage, the algorithm ensures preferable matching precision, and accelerates computational specd.
