基于核心点定位的部分指纹检测
Partial Fingerprint Detection Using Core Point Location
摘要：
在生物特征识别中，基于指纹的身份识别机制已被广泛接受。自动指纹识别/验证技术在许多民用和法医应用中被广泛采用。在法医学应用中，指纹通常是不完整的、破碎的、不清晰的或退化的，这被称为部分指纹。指纹识别/验证在很大程度上受到处理部分指纹的问题的困扰。本文提出了一种基于核心点定位的局部指纹检测方法。我们的技术是特别有用的，在采集阶段，以确定用户是否需要重新对齐手指，以确保一个完整的捕获的指纹区域。结果非常准确，如结果部分所示。
英文摘要：
In Biometric identification, fingerprints based identification has been the widely accepted mechanism. Automated fingerprints identification/verification techniques are widely adopted in many civilian and forensic applications. In forensic applications fingerprints are usually incomplete, broken, unclear or degraded which are known as partial fingerprints. Fingerprints identification/verification largely suffer from the problem of handling partial fingerprints. In this paper a novel and simple approach is presented for detecting partial fingerprints using core point location. Our techniques is particularly useful during the acquisition stage as to determine whether a user needs to re-align the finger to ensure a complete capture of fingerprint area.This technique is tested on FVC-2002 DB1A. The results are very accurate which are presented in the Results sections.
