基于单片机的人脸识别系统

摘 要随着社会的进展，各个方面对快速有效的自动身份验证的要求日益迫切。由于生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份验证的理想依据。这其中，利用人脸特征又是最自然直接的手段，相比其他生物特征,它具有直接、友好、方便的特点,易于为用户接受。 人脸识别是一个涉及面广且又很有挑战性的讨论课题,近年来关于人脸识别的讨论取得了较大的进展.关键词:人脸识别，AT89C51 单片机,液晶显示器AbstractAs the development of the society， there are increasing demands in automatic identity check。 Since some biological characteristics are intrinsic and stable to people and are strongly different from one to the others ， they can be used as features for identity check 。 Among all the characteristics of human, the characteristics of face are the most direct tools which are friendly and convenient and can easily be accepted by the customers.Face recognition is an extensive and challenging research problem. Recently, significant progresses have been made in the technology of the face recognition.Key word：AT89C51 MCU，human face recognition,LCD目录\摘 要......................................................ⅠAbstract.....................................................Ⅱ第 1 章 绪 论.................................................41.1 人脸识别系统的背景和意义................................41.2 国内外人脸识别系统的讨论现状............................61。2。1 国外的进展概况...................................61。2。2 国内的进展概况..................................61。3 本论文的内容..........................................71.4 本文的任务.............................................7第 2 章 人脸图片识别总体方案设计...............................72。1 系统硬件结构...........................................7第 3 章 系统硬件部分的设计与实现...............................93. 1 硬件设计基本流程.......................................92.2 单片机的进展概况及其选择...
