基于中心点的指纹匹配算法的研究

Research on Fingerprint Matching Algorithm Based on the Core

研究了一种基于指纹中心点的指纹匹配算法.该算法将指纹的中心点来确定指纹匹配时的参考点,指纹的中心方向为初始方向,在此基础上所有的特征点用极坐标表示.该方法降低计算量,并提高了匹配的准确性.

To overcome the problem of computing solely in fingerprint matching, an algorithm based on the fingerprint core is studied in this paper. All minutiae are presented by the polar coordination. The approach decides the point of reference according to the core and looks the center orientations as the original orientations. This approach can accelerate the matching process and improve the matching precision.
