【摘要】 由于指纹图像中存在非线性变形和噪声干扰,当前的指纹识别系统不能满足某些系统要求保持很低的误接受率(FAR)的同时达到较低误拒绝率(FRR)的要求。提高识别性能的一个有效的方法是融合多个模板和多个指纹的数据融合技术。该文研究的一种多印痕指纹数据融合技术能够改善系统性能。通过实验证明了这种数据融合技术能够有效提高系统性能,可以使系统在保持低误接受率的条件下降低误拒绝率。更多还原

【Abstract】 Current fingerprint verification systems can not meet some applications which require both False Accept Rate(FAR)and False Reject Rate(FRR)being very low because there are nonlinear transformation and noise interference in fingerprint images.An effective method to improve the system performance is to apply the multi_template or multi_impression data fusion technology.This paper proposes a multi_impression data fusion technology for fingerprint verification,which can improve system performance.It can lower system false reject rate while keeping very low system false accept rate.更多还原
