面部识别又称人脸识别、面像识别、面容识别等等，面部识别使用通用的摄像机作为识别信息获取装置。以非接触的方式获取识别对象的面部图像，计算机系统在获取图像后与数据库图像进行比对后完成识别过程。面部识别是基于生物特征的识别方式 ，与指纹识别等传统的识别方式相比，具有实时、准确、高精度、易于使用、稳定性高、难仿冒、性价比高和非侵扰等特性，较容易被用户接受。-Face recognition is also called face recognition, face recognition, facial recognition, etc., and face recognition uses a general-purpose camera as identification information acquisition means. The face image of the recognition object is acquired in a non-contact way, and the computer system completes the recognition process after acquiring the image and comparing it with the　image. Facial recognition is based on the recognition of biological features. Compared with the traditional identification methods such as fingerprint recognition, facial recognition is easy to use, high accuracy, high stability, high cost performance and non-intrusive characteristics.
