1、1．打开MicrosoftVisualStudio2008，新建一个Win32控制台项目；2．配置好项目的包含文件和库文件；3．将……OpenCVdatahaarcascades中的haarcascade_frontalface_alt.xml拷贝到所建项目的文件夹中；4．然后添加代码：#include"stdafx.h"#include#includeIplImage*image;IplImage*copyimage;staticCvHaarClassifierCascade*cascad

2、e=0;staticCvMemStorage*storage=0;constchar*cascade_name="haarcascade_frontalface_alt2.xml";//先要将次文件从OpenCVdatahaarcascades文件夹中拷贝到项目文件夹中voiddetect_and_draw(IplImage*img);//函数声明int_tmain(intargc,_TCHAR*argv[]){cascade=(CvHaarClassifierCascade*)cvLoad(cascade_name,0,0,

3、0);//加载人脸检测所用的分类器if(!cascade){fprintf(stderr,"ERROR:Couldnotloadclassifiercascade");return-1;}storage=cvCreateMemStorage(0);//动态存储结构，用来存储人脸在图像中的位置image=cvLoadImage("F:\TestImages\faceScene.bmp");if(!image)return-1;cvNamedWindow("OriginalImage",1);cvShowImage("Orig

4、inalImage",image);detect_and_draw(image);//对加载的图像进行检测cvWaitKey();image=NULL;//如image是用cvCreateImage()创建的，那么用cvReleaseImage()释放;若不是"创建"的,就不能“释放”cvDestroyWindow("Original");cvDestroyWindow("result");otherstaffoftheCentre.Duringthewar,ZhuwastransferredbacktoJiangxi,andDi
