基于Opencv的人臉檢測(cè)程序源代碼(可運(yùn)行

1、1 打開(kāi)Microsoft Visual Studio 2008，新建一個(gè)Win32控制臺(tái)項(xiàng)目；2 配置好項(xiàng)目的包含文件和庫(kù)文件；3 將OpenCVdatahaarcascades中的haarcascade_frontalface_alt.xml拷貝到所建項(xiàng)目的文件夾中；4 然后添加代碼：#include stdafx.h#include #include IplImage* image; IplImage* copyimage;static CvHaarClassifierCascade* cascade = 0;static CvMemStorage* storage = 0;const

2、char* cascade_name =haarcascade_frontalface_alt2.xml; /先要將次文件從OpenCVdatahaarcascades文件夾中拷貝到項(xiàng)目文件夾中void detect_and_draw( IplImage* img ); /函數(shù)聲明int _tmain(int argc, _TCHAR* argv)cascade = (CvHaarClassifierCascade*)cvLoad( cascade_name, 0, 0, 0 ); /加載人臉檢測(cè)所用的分類(lèi)器if( !cascade )fprintf( stderr,ERROR: Could

3、not load classifier cascaden );return -1;storage = cvCreateMemStorage(0); /動(dòng)態(tài)存儲(chǔ)結(jié)構(gòu)，用來(lái)存儲(chǔ)人臉在圖像中的位置image = cvLoadImage( F:TestImagesfaceScene.bmp );if( !image ) return -1;cvNamedWindow( Original Image, 1 );cvShowImage( Original Image, image);detect_and_draw( image ); /對(duì)加載的圖像進(jìn)行檢測(cè)cvWaitKey();image = NULL;

4、 /如image是用cvCreateImage()創(chuàng)建的，那么用cvReleaseImage()釋放;若不是創(chuàng)建的,就不能“釋放”cvDestroyWindow(Original);cvDestroyWindow(result);return 0;void detect_and_draw( IplImage* img)static CvScalar colors = 0,0,255,0,128,255,0,255,255,0,255,0,255,128,0,255,255,0,255,0,0,255,0,255;double scale = 1.3;copyimage=img;IplImage

5、* gray = cvCreateImage( cvSize(copyimage-width,copyimage-height), 8, 1 );cvCvtColor( copyimage, gray, CV_BGR2GRAY );cvClearMemStorage( storage );if( cascade )/*函數(shù)cvHaarDetectObjects檢測(cè)圖像中的目標(biāo)，由OpenCV提供。*/CvSeq* faces = cvHaarDetectObjects( gray, cascade, storage, 1.1, 2, CV_HAAR_DO_CANNY_PRUNING ,cvSize(20, 20) );for( int i = 0; i total : 0); i+ )CvRect* r = (CvRect*)cvGetSeqElem( faces, i );cvRectangle( copyimage, cvPoint(r-x,r-y),cvPoint(r-x+r-width,r-y+r-height), CV_RGB(255,0,0), 3 );cvNamedWindow( resu
