基于结构特征的指纹细节点匹配算法

n Algorithm of Matching Fingerprint Minutiae Based On Structure Feature

中文摘要英文摘要

提出了一种新的指纹特征匹配方法。首先定位指纹图像的中心点,然后提取细节点,并计算其与中心点的角度差以及到中心点所穿越的脊线数,将此作为特征向量与细节点特征结合,最后根据穿越的脊线数和角度差对细节点进行匹配。实验表明该算法运行速度较快,有较强的抗噪声与图像形变的能力,能有效地提高指纹图像匹配的准确程度。

new approach to match fingerprint feature is presented in this paper. First, locate the core point of the fingerprint image, then extract the minutiae ,get the D-value of angles between minutiae and the core, and compute number of ridge lines the minutiae across to the core , regarding these values as feature vectors combined with minutiae feature, finally, match the minutiae through ridge lines and the D-value of angles . The experiment shows that this approach is fast and has the ability to resist the noise and nonlinear deformations and can extract the structure feature information of the fingerprint image.
