我是靠谱客的博主犹豫大白，最近开发中收集的这篇文章主要介绍opencv之4.1，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

#include "stdafx.h"
#include "cv.h"
#include "cxcore.h"
#include "highgui.h"

int _tmain(int argc, _TCHAR* argv[])
{
    cvNamedWindow("frame");
cvNamedWindow("frame_gray");
cvNamedWindow("frame_canny");
    CvCapture *capture=cvCreateFileCapture("1.avi");
IplImage *frame;
IplImage *frame_gray=cvCreateImage(cvSize((int)cvGetCaptureProperty(capture,3),(int)cvGetCaptureProperty(capture,4)),IPL_DEPTH_8U,1);
    IplImage *frame_canny=cvCreateImage(cvSize((int)cvGetCaptureProperty(capture,3),(int)cvGetCaptureProperty(capture,4)),IPL_DEPTH_8U,1);
    while((frame=cvQueryFrame(capture))!=NULL)
{
cvCvtColor(frame,frame_gray,CV_RGB2GRAY);
     cvCanny(frame,frame_canny,0,40,3);
     cvShowImage("frame",frame);
cvShowImage("frame_gray",frame_gray);
cvShowImage("frame_cannny",frame_canny);
char c;
if(c==27) break;
}
   cvReleaseImage(&frame);
   cvReleaseImage(&frame_gray);
   cvReleaseImage(&frame_canny);
   cvReleaseCapture(&capture);
   cvDestroyWindow("frame");
   cvDestroyWindow("frame_gray");
   cvDestroyWindow("frame_canny");
return 0;
}
