摘要

介绍了基于邻域编码的纹线跟踪技术及其纹线跟踪过程

在此基础上

完善了指纹图像后处理算法

提取了指纹细节特征。在完全细化的指纹图像上

利用纹线跟踪技术

剔除了可能的伪特征点

保留了真实的细节特征点

指纹图像后处理效果十分理想

达到了指纹特征准确提取和特征点集准确获取的目的

为后续的指纹匹配工作打下了良好的基础。

Abstract

The ridgelines tracing technology based on neighbor-coding and its tracing process are introduced.On the base of it

the fingerprint image post-processing algorithms are improved and the fingerprint minutiae are extracted.By eliminating the possible false minutia and extracting the genuine minutiae on entirely-thinned fingerprint image

the effect of post-processing is perfect.The aim can be achieved that fingerprint minutia correctly extracting and minutia collection exactly founding.It can provide an ideal prepare for next work-fingerprint matching.
