Smile detector refinement method
The mouth rectangle is surrounded by four feature points: right mouth corner, center point of upper lip, left mouth corner, center point of lower lip. Actually we would expand the rectangle wider and higher to one standard deviation in each direction.
Smile detector Real Time Case
It shows a sequence of images and their correlation value corresponding to the initial mouth pattern. These images give us some level of confidence that using correlation to identify the neutral or smile expression is possible.
Main Output of Smile Detector
We have proposed a fast and generally low misdetection and low false alarm video based method of smile detector.
