基于haar级联分类器的opencv人眼识别程序，思路是先识别人脸，然后以人脸为ROI识别人眼。-Haar cascade classifier based on opencv human eye recognition program, the idea is to recognize faces, and then face the human eye to identify the ROI.

利用opencv资源库里自带的lbpcascade_animeface.xml，对普通人脸进行识别，如果有数据库的话，也可以自己训练学习，提取人脸特征，进行学习(We use the lbpcascade_animeface.xml in opencv repository to recognize normal faces. If there are databases, we can also train ourselves to learn, extract facial features
