摘要
指纹特征的提取在指纹自动识别系统中是一个必不可少的重要环节。指纹特征通常包括指纹奇异点和细节特征点。文章在给出了一种计算指纹方向图的新方法基础上提出了奇异点的提取新方法。实验表明该方法能够准确地提取出指纹的奇异点，并具有较强的抗干扰性。针对指纹图象质量较差时，存在大量的伪细节特征点，文章提出了一种新的细节特征点验证的方法，获得了良好实验结果。
： The extraction of fingerprint features is an necessary important step in automatic fingerprint recognition system．The fingerprint features usually include singular points and minutiae．A new method to detect singular points is presented in this article based on an new approach to obtain fingerprint orientation image．The experiment result shows that this new method can correctly extract fingerprint singular points，obtaining relative strong anti－interference ability．For the case of relative poor quality of fingerprint image，in which there are many false minutiae，a new method to verify the minutiae is presented with relative good experiment results in this article，
