摘要
指纹预处理算法是指纹识别的关键技术之一,是提取指纹特征信息的基础.系统阐述了指纹识别系统的结构、流程及相应算法实现,重点讨论了预处理过程的几种算法,对每个功能模块和算法均给出了处理结果.整套预处理算法在选择单元算法方面充分考虑了局部最优性与全局兼容性问题;通过项目实践可看出其处理结果比较理想,程序的移植性较好,可搭配其他特征提取算法和匹配算法.
As one of the key fingerprint identification technology, fingerprint preprocessing algorithm builds up foundation of feature data extraction. In the paper, the construction, process and corresponding algorithm realization of the fingerprint identification system are systematically demonstrated. Several algorithms of the preprocessing technology are discussed in detail, and the processed results of each functional module and algorithm are given. For each unit algorithm, the suboptimization and global compatibility are fully looked after on both sides. In the practice, the set of algorithms has an ideal processing result and a good transplantability and can work with other algorithms of feature extraction and matching.
