一种利用曲线结构和三角法进行指纹快速点模式匹配的算法研究与实现

针对指纹的点模式匹配方法中如何确定两枚指纹的比对基准参考点问题，提出了一种基于指纹的纹线结构与三角形方法相结合的方法。实验结果表明，该算法在保留了点模式匹配方法优点的同时有效地提高了匹配速度。

A Fast Fingerprint Matching Algorithm Research and Implement Based on Curve Structure and Triangle Method

In the light of the barrier for determining the comparing reference points of two fingerprint images in the point pattern matching, a fast matching algorithm, which can find out the reference point efficiently based on integrated combining between fingerprint curve structure and triangle method, is presented. Through the experiment of verifying fingerprint matching algorithm, this algorithm is still of invariability of rotating and displacing, and it is fast to find out the reference point, fast to match, and of an attribute of resistance when trait points lost a few or some false trait points appear.
