利用opencv，adaboost+haar特征实现人脸识别的python小程序-a program use opencv and haar feature to detect face a picture

用HAAR和Adaboost训练并检测行人，其中存在一点BUG，需要安装LIB-SVM(Using HAAR and Adaboost to train and detect pedestrians, there is a bit of BUG, and LIB-SVM needs to be installed.)

用adaboost对人脸检测，利用haar特征对积分图像进行训练，得到强弱分类器(Face detection is done by AdaBoost, and integral image is trained by Haar feature, and the strong and weak classifier is obtained.)
