本程序主要是实现人脸是被的功能，并对识别出的人脸进行处理保存，使用了opencv数据库，可以直接运行-This program is to achieve the main face to be the function, and identify the human face processing to save, use the opencv database can be run directly

该程序可以追踪人脸并检测人脸的面部特征，从而达到识别人脸的功能，利用了OPENCV的图形处理功能，自动追踪人脸，检测与已载入的数据库进行匹配，进行识别，最终会给出检测结果。(The program can track the face and detect the facial features of the face, so as to achieve the function of recognizing the face, the use of OPENCV graphics proces

本程序用到了opencv 中的扩展库opencv contrib, 先用take.cpp来获取自己的数据库，然后在用tria.cpp来训练能检测自己的脸的检测器，再运行recon.cpp来进行人脸检测。(This program uses the extension library opencv contrib in OpenCV. First, take.cpp is used to get its own database, then tria.cpp is used to train th
