| 摘 要： | 指纹匹配是自动指纹识别中的重要环节。首先介绍了指纹匹配中已有的一些方法和指纹匹配需要解决的问题,继而提出了一种基于中心区域基准点的指纹匹配算法,通过搜寻中心区域的细节点集合定位基准点对,以此计算旋转和平移参数,最后统计姿势矫正后的匹配点个数来实现两枚指纹的比对。实验结果表明,针对图像质量不同的两个指纹库,该算法能有效地抵抗图像噪声,准确定位基准点,达到较高的准确率。

| Abstract: | Fingerprint matching is an important issue in automatic fingerprint identification system.In this paper we describe some fingerprint matching algorithms that have been delivered and some problems of them to be resolved,and then propose a fingerprint matching algorithm based on reference points of the central area.The pair of the reference points can be located by scanning two minutia point sets in central area,and the parameters of rotation and translation are calculated accordingly.Finally,the intercompari... |
