這次的作業在做gray沒有什麼問題
但是在bw等等不知道為什麼就是會閃動以及顯示不出
後來成功解決閃動的問題
以下是重要的程式碼

pImg2 = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 3);
  gray = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);
  bw = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);
  pCannyImg = cvCreateImage(cvGetSize(pImg), IPL_DEPTH_8U, 1);



     pImg=cvQueryFrame(capture);
     cvResize(pImg,dst,CV_INTER_NN);
     cvCvtColor(pImg, gray, CV_BGR2GRAY);
     cvThreshold( gray, bw, 160, 255, CV_THRESH_BINARY );
     cvThreshold( pImg, pImg2, 127, 255, CV_THRESH_BINARY );
     cvCanny(gray, pCannyImg, 50, 150, 3);

為圖片取得記憶體等等的程式碼
視訊解析感覺相當有趣

重點程式碼:



  pImg2 = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 3);
  gray = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);
  bw = cvCreateImage(cvSize(pImg->width,pImg->height), IPL_DEPTH_8U, 1);
  pCannyImg = cvCreateImage(cvGetSize(pImg), IPL_DEPTH_8U, 1);
cvNamedWindow("src", 1);
cvNamedWindow("gray",1);

    while(1)
    {
     pImg=cvQueryFrame(capture);

        cvResize(pImg,dst,CV_INTER_NN);

cvCvtColor(pImg, gray, CV_BGR2GRAY);
cvThreshold( gray, bw, 130, 255, CV_THRESH_BINARY );
cvThreshold( pImg, pImg2, 127, 255, CV_THRESH_BINARY );


cvCanny(gray, pCannyImg, 50, 150, 3);
