This paper proposes a Person-Independent Facial Expression Space (PIFES) to analyze and synthesize facial expressions based on Supervised Locality Preserving Projections (SLPP), which aligns different subjects and different intensities of facial expressions on one generalized expression manifold. Interactive curves of different patterns are generated according to the input facial expression image sequence, and target responsive expression images are synthesized for different emotions. In order
