摘要
针对现有匹配算法中存在的问题 ,在已有结构化匹配方法的基础上加以改进 ,提出一种分段式匹配方法 ,并就特征向量的构造作出详细介绍 .经实验证明该方法有效而快速 ,可应用于实际的指纹自动识别系统中 .
According to the problems in the matching algorithm existed, this paper proposed a grading-match method based on the modified structural matching method, and descripted how to construct the feature vectors in detail. By the test result it is proved that this is an effective and quick method which can be applied to the practical fingerprint automatic identification system.
