摘要
研究了指纹图像的预处理、特征提取及特征匹配这三种算法。介绍了指纹和自动指纹识别系统的相关知识,详述其各组成单元;采用了基于三角形基准点定位匹配的算法,以弥补细节点指纹匹配算法过于依赖中心点的不足;并在VC++6环境下开发了自动指纹识别系统软件,性能测试结果表明,该系统能较好地实现自动指纹识别功能。
The research of the automatic fingerprint identification system, briefly , including three algorithm for fingerprint image preprocessing, feature extraction and feature matching. First ,it introduce the knowledge of fingerprint and automatic fingerprint identification system, then describes in detail the units. In order to solve the insufficiency of the minutiae of fingerprint matching algorithm relies too much on the center point, algorithm triangular locating reference point. Finally, in the VC ＋-t-6 development the fingerprint identification system software, and test its performance. The system realize the function of automatic fingerprint identification well.
