opencv php,OpenCV应用实例

1.加载图片#include "stdafx.h"

#include "highgui.h"

#include

using namespace std;

using namespace cv;

int main( int argc, char** argv ) {

IplImage* img = cvLoadImage("lena.jpg");//加载图片

cvNamedWindow("Example1", CV_WINDOW_AUTOSIZE );

cvShowImage("Example1", img );

cvWaitKey(0);

cvReleaseImage( &img );

cvDestroyWindow("Example1");

}

2.加载视频#include "stdafx.h"

#include "highgui.h"

#include

using namespace std;

using namespace cv;

int main( int argc, char** argv ) {

cvNamedWindow( "Example2", CV_WINDOW_AUTOSIZE );

//CvCapture* capture = cvCaptureFromAVI( argv[1] ); // either one will work

CvCapture* capture = cvCreateFileCapture("E:\\视频素材\\aaa.avi");

IplImage* frame;

while(1) {

frame = cvQueryFrame( capture );

if( !frame ) break;

cvShowImage( "Example2", frame );

char c = cvWaitKey(33);

if( c == 27 ) break;

}

cvReleaseCapture( &capture );

cvDestroyWindow( "Example2" );

}
