  • how is this related to c++ or c? if you are using some specific library mention that. C++ or C doesn't have any concepts you mentioned in the question. – Naveen Feb 20 '12 at 09:46
  • i am using opencv library with microsoft visual studio. – Abdullah x Feb 20 '12 at 09:50
  • The question is on-topic ([this earlier question](http://stackoverflow.com/questions/1707620/viola-jones-face-detection-claims-180k-features) was too), but it is very poorly phrased. – MSalters Feb 20 '12 at 12:52

CascadeClassifier haarCascade;

Mat frame;
Rect roi;

Mat roiImg(frame, roi);

vector<Rect> objects;
haarCascade.detectMultiScale(roiImg, objects);
