指纹自动识别与人工识别的差异及人机配合策略

Strategy of Man-machine Coordination by Difference of Computerbased Automatic Fingerprint Identification from Artificial Recognition

一般而言,技术人员和指纹自动识别系统各自在确定指纹特征、判断两枚指纹相似程度时,采用的方式、方法不完全相同。笔者结合多年的工作经验,对指纹特征提取及指纹特征识别等核心问题展开分析,给出指纹自动识别系统与人工指纹识别在问题判别及处理上的差异之处。在此基础上,针对指纹自动识别系统可能出现特征标注偏差、遗漏特征或者出现虚假特征的情况,总结出人机配合的指纹识别策略。

Generally,technicians adopt somewhat different approaches and methods from AFIS(Automatic Fingerprint Identification System)when they independently judge the similarity of two fingerprints based on the determination of fingerprint characteristics.In this paper,the analyses were developed at extracting and recognizing fingerprint features according to our experience,therefore revealing the difference on fingerprint query and processing between AFIS and artificial recognition.Thus,the strategy of man-machine coordination has been concluded against the incidence where AFIS made the fingerprint features labeled with deviation,left out and even erred.
