摘要
指纹匹配技术分为两种:基于细节点的匹配和基于纹线相关性的匹配。文章属于基于细节点的匹配,采用细节点及其临近的5个点形成局部矢量。每枚指纹分解成若干个这样的局部矢量。于是,两枚指纹的匹配就转变为矢量数组的匹配。
There are two fingerprint matching technologies: matching based on minutia and matching based on the relation among ridges. This paper belongs to the former, a minutia and its five near minutia form a local vector, each fingerprint is decomposed to several local vectors. So, the matching between two fingerprints is changed into the matching between two matrixes of vector.
