A Unified Probabilistic Framework for Spontaneous Facial Action Modeling and Understanding

Facial expression is a natural and powerful means of human communication. Recognizing spontaneous facial actions, however, is very challenging due to subtle facial deformation, frequent head movements, and ambiguous and uncertain facial motion measurements. Because of these challenges, current resea...
