摘要
针对传统访问控制系统不能达到满意的安全防范效果,本文提出通过识别人脸的面部图像的方法来访问,从而实现对身份的双重检验的新思想。系统主要技术包括:用基于小波变换的PCA实现特征抽取,用最近邻域作为识别判据,以类内相似度为最终认定条件。
For traditional access control system can't attain satisfying safety, a new method is proposed to apply face recognition technology to access control system. The following methods are used in the system: PCA based on wavelet transform for face feature extraction, NNA method as classifier in face recognition, within-class similarity as recognition determinant.
