這次上課學到


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


cvCvtColor(frame, gray, CV_BGR2GRAY);
 cvThreshold(gray, bw, 63, 255, CV_THRESH_BINARY );
 cvThreshold( frame, pImg2, 127, 255, CV_THRESH_BINARY );
cvCanny(gray, pCannyImg, 50, 150, 3);

彩色轉成灰階黑白還有線條

滿有趣的
