I'm using OpenCV 2.4.10. I can detect pair eyes and mouth for alignment with fair accuracy rate. Here is my situation. https://www.youtube.com/watch?v=0ZY5U...

My problems are :
1. Eyes detection return false eye. I got 3rd eye in nearby the correct one.
2. Neo's mouth has been dropped on many frames.

Any help would be appreciated.

@berak. Hello berak. Do you have any idea? Any keyword I can find out on my own?

you could try to increase the minNeighbours param in cascade.detectMultiScale(), until you start to miss eyes.

@berak. I though your eye answer will rely on face geometry ratio or length of them. I am now observing the variation of them. Let me try and return to forum again. Do you think mouth is impact by face area? Since my Neo detected face has very near edge to the mouth.
