该文主要研究了基于细节点的方法来提取指纹特征特点,在后处理部分.结合细化指纹图像中细节特征点固有的分布规律,提出了一种新的滤除指纹细节伪特征点的方法.在记录特征点信息部分,该文提出了一种新的记录特征点信息的方法.该方法不依赖于指纹中心点的录入并将特征点之间的距离用纹线数表示,从而增加了算法的鲁棒性.

This paper focus on the study of the fingerprint image's feature extraction approach, which is based on minutia features. In the aspect post-processing, a new approach to diminate false features is presented. The elimination algorithm of false features is based on the distributing disciplinarian of fingerprint features. In the noting information of features, we raise a new method. The method doesn't depend on the existence of the center of fingerprint in images and uses the ridge count as the distance between two features.
