| 摘 要： | 提出了一种新的基于线模式的指纹图像细节点匹配算法,这种算法先分别找出最佳匹配点对,确定相对旋转角度,较快地确定两个指纹的相关性,之后再搜索漏的匹配点对,去掉错误的匹配点对。算法受指纹增强、后处理的影响较小,细节点相似程度受其邻域细节点影响较小。介绍了算法的具体实现方法,并用实际指纹数据进行了测试。初步测试的结果表明,此算法是指纹图像细节点匹配的一种有效算法。

| Abstract: | In this paper,a new algorithm for fingerprint image minutiae matching based on line pattern is proposed.Firstly,we search the best minutiae sets and determine the rotary angle,obtain the correspondence of the two fingerprints.Then,we search the lost sets,delete the wrong sets．The effect affected by fingerprint enhancement and post processing is small．The minutiae’s correspondent level affected by its neighborhood is also small．This paper describes the steps of the algorithm and tests its performance using real fingerprint images．The experimental results show the proposed algorithm is effective. |
