| 摘 要： | 设计了一种基于人脸识别的门禁系统。该系统从前端摄像头获取人脸图像,在PC机上完成识别,然后给单片机发送命令来控制门禁系统。软件上首先利用小波变换对人脸图像进行2次小波分解,然后对低频分量进行离散余弦变换(DCT)提取特征值,最后利用欧氏距离和最近邻分类器进行识别。结果表明该系统构建简单、方便,识别速度快且准确率较高。

| Abstract: | An access control system was designed based on face recognition.The system gets face images from the front camera,finishes identification in PC,then sends commands to the MCU(Micro Controller Unit) to control the access control system.First we use wavelet to transform face image twice,then extract eigenvalue by using discrete cosine transform(DCT) to transform the low frequency components,finally identify the face by using euclidean distance and nearest neighbor classifier.The results show that the system c... |
