摘要:

基于韦伯二值感知特征的局部描述符,提出一种指纹活性检测方法。该方法包含两部分:根据韦伯定理提取视觉感知特征的局部二值差分激励,以及从中心对称像素对提取梯度方向特征的局部二值梯度方向。在2011年和2013年指纹活性检测竞赛的数据库上,使用支持向量机分类器对提取的特征向量进行训练和测试,实验结果表明了该方法进行指纹活性检测的有效性。

Abstract:

Based on Weber binarized perception features (WBPF), we propose a fingerprint liveness detection method. It consists of two components: local binary differential excitation (LBDE) for extracting perception features by Weber's law, local binary gradient orientation (LBGO) for extracting gradient based orientation features. The features are used to train SVM classifiers on two publicly available databases used in the Fingerprint Liveness Detection Competition 2011 and 2013. Experimental results show that the proposed method outperforms the state-of-the-art liveness detection techniques.
