| 摘 要： | 在对指纹匹配算法进行了深入研究及总结现有算法优缺点的基础上,提出了新的基于扇区划分的细节点采样指纹匹配算法。本算法以指纹图像参考点为中心,分扇区对细节点数目进行采样统计以构造新的指纹特征向量,再利用距离最小准则进行指纹匹配。实验结果表明,本算法有效提高了指纹图像的匹配效果和运行速度。

| Abstract: | In this paper,some fingerprint matching algorithms are researched deeply.A new fingerprint matching algorithm based on sector-sampling is proposed.The algorithm takes fingerprint image reference point as center point and divides the interested region into many sectors.The number of minutiae in sector is counted to construct new fingerprint feature vectors.Then we use the minimum distance criteria for fingerprint matching.The experiment results demonstrate that the new method can enhance matching effects and running speed of fingerprint processing. |
