Hi.
I have a code that detect just open eyes and draws a circle around it, Now I need a variable like "A" that should works as a flag that means if an open eye has been detected it should be A=1, and when there is no eye in the picture A=0, to use in following codes. here is a part of my codes :
face_cascade.detectMultiScale(gray_img, faces, 1.1, 10, CV_HAAR_SCALE_IMAGE | CV_HAAR_DO_CANNY_PRUNING, cvSize(0,0), cvSize(300,300));
for( int i=0; i < faces.size(); i++){
Point pt1(faces[i].x+faces[i].width, faces[i].y+faces[i].height);
Point pt2(faces[i].x, faces[i].y);
Mat faceROI = gray_img(faces[i]);
haarcascade_eye.detectMultiScale(faceROI, eyes, 1.2, 40, 0 | CV_HAAR_SCALE_IMAGE, Size(30,30));
for(size_t j=0; j
