Complex Direction Feature Based Fast Fingerprint Verification
基于复合方向特征的快速指纹验证

Because of high restriction on False Reject Rate,False Accept Rate,computational time cost and template size,fingerprint verification is a challenging task.A novel feature named complex direction feature is proposed in this paper,which consists of ridge rotation direction and four local relative directions.The fingerprint verification consists of two stages: complex direction feature based minutiae alignment,which speeds up alignment;matching score calculation by complex direction feature,which makes matching more robust.Experiments were performed on the fingerprint database used by Fingerprint Verification Competition,and the experimental results show that the proposed algorithm can achieve reliable and fast fingerprint verification.
