| 摘 要： | 通过改进指纹识别流程和预处理算法,使指纹识别系统能有较强的伪指纹判别性能.在指纹图像预处理环节计算多个前景灰度特征值,包括图像质量特征值、材质特征值和信息量特征值.选取特定的阈值,对前后采集的指纹图像特征值进行比较,判别是否为伪指纹图像.实验结果证明了该方法的有效性.

| Abstract: | Throung improved fingerprint identification process and pre-processing algorithm,make the fingerprint identification system has stronger performance to detect ersatz fingerprint.Calculate some foreground grayscale eigenvalues in the pre-processing of the fingerprint image,including image quality eigenvalues, material eigenvalues and information eigenvalues.Seleet some specific threshold, compare the fingerprint image eigenvalues of before and after, to detect it is ersatz fingerprint image or not. |
