The method also comprises identifying a plurality of candidates representing mouth corners. The method also comprises generating parabolas between each pair of candidates representing mouth corners. The method also comprises analyzing contour of at least one of the parabolas to determine whether the mouth curves substantially upward to form a smile or curves substantially downward to form a frown.
