基于android的手机人脸点名系统毕业设计(论文)介绍

       摘要:人脸识别作为生物识别技术的一种,具有无接触、安全和方便的特点。人脸 识别技术广泛应用于人机交互、交易认证及安防等领域,一直是生物识别技术研 究的热点。

近年来,随着移动互联网的发展,智能手机平台获得了长足的发展。然而, 手机钱包、手机远程支付等新应用的出现使得手机平台的安全性亟待加强。传统 的密码认证存在易丢失、易被篡改等缺点,人脸识别不容易模仿、篡改和丢失, 因而适用于手机安全领域中的应用。

人脸识别包括人脸检测、特征定位、人脸归一化、特征提取和特征识别。本 文研究了人脸识别中的关键问题,并在Android平台上实现了基于图像的人脸识 别系统。

基于android的手机人脸点名系统毕业设计(论文)研究内容:

 识别首先需要将人脸从背景区域中分割出来,之后提取人脸区域的特 征,最后进行认证和识别【2】。人脸识别包含图像预处理、人脸检测、特征定位、 人脸归一化、特征提取和特征识别等多个子过程,如图1.1所示。其中,人脸检 测、特征定位、人脸归一化和特征提取是人脸识别研究的重点,决定着人脸识别 系统的最终性能。人脸识别中的各个子过程之间并不是相互独立的,而是相互依 存的、相互依赖的,当前子过程产生的结果直接影响下一个子过程的实施。
