最简单的ADABOOST人脸检测例程。COPY运行，前提是你配置好OpenCV环境

#include "cv.h"#include "highgui.h"#include "stdio.h"void main(){IplImage* img = NULL;IplImage* cutImg = NULL;CvMemStorage* storage = cvCreateMemStorage(0);//CvHaarClassifierCascade* cascade = (CvHaarClassifierCascade*)cvLoad("data.xml", 0, 0, 0);CvHaarClassifierCascade* cascade = (CvHaarClassifierCascade*)cvLoad("haarcascade_frontalface_alt2.xml", 0, 0, 0);CvSeq* faces;char save_path[100];char path[100];int j;int index = -1;for (int i = 5 ; i <= 100; i++){sprintf(path,"..\\20140622jiezhen\\%d.bmp", i);sprintf(save_path,"..\\GABCUT\\%d.bmp", i);img = cvLoadImage(path, 0);faces = cvHaarDetectObjects(img, cascade,  storage, 1.2, 2, 0, cvSize(25,25) );if (faces->total == 0)continue;cvSetImageROI(img, *((CvRect*)cvGetSeqElem( faces, 0))); cvSaveImage(save_path, img);            cvResetImageROI(img);   }}

这里用的xml文件是openCV已经训练好的人脸参数，可以在OpenCV安装目录下搜索*.xml得到。程序就是将检测到的人脸图像截图保存。我用这个程序来快速检测自己训练的效果。分享给大家。
