I am using opencv 3.0.0 on a windows machine with visual studio 2012.. i have written a code regarding face detection using HAAR cascade classifier.The problem i am facing is that,in real-time face detect,bounding box is flickering around face,it is not holding accurate and static(stable) position around face,at each frame coordinates of bounding box is changing by approx(3-5 px).The box isn't stable about face .can someone help on this?
