System and method for expression mapping |
摘要 |
A system and method for mapping facial expressions. Facial expressions exhibit not only facial feature motions, but also subtle changes in illumination and appearance (e.g., facial creases and wrinkles). These details are important visual cues, but they are difficult to synthesize. Traditional expression mapping techniques consider feature motions while the details in illumination changes are ignored. A novel technique for facial expression mapping is presented. The illumination change of one person's expression is captured in what is called expression ratio image (ERI). Together with geometric warping, an ERI is mapped to any other person's face image to generate more expressive facial expressions
