摘　　要：提出了一种基于二值指纹局部特性提取细节点的算法。该算法与快速并行细化算法相比,在提取细节点准确性相当的情况下,速度大为提升。使用FVC2002指纹数据库测试表明,该算法可靠、高效。In this paper, an algorithm is proposed to extract minutiae based on local features of binary fingerprint image. Compared with fast parallel thinning, which has the same veracity of minutiae extraction, the proposed method improves the speed greatly, and is tested in FVC2002 fingerprint database. The experimental results prove the effectiveness and reliability of the proposed algorithm.
