FACIAL ANIMATION ANALYSIS
Rahma Mohsen Ragab;
Abstract
ABSTRACT
Making realistic facial animation is one of the most challenging research topics in facial animation field because producing realistic photo and sentimental virtual characters require a combination of face modeling, animating, and rendering. Techniques that commonly used for facial animation are in need of naturalism. The most popular expression coding systems are FACS and MPEG-4 Facial Animation. FACS (Facial Action Coding system) is a landmark technique that enables remarkable improvements in making realistic facial animations. Where MPEG-4 (Moving Pictures Experts Group-4) Facial Animation provides a standard way of encoding facial actions by defining various parameters for a talking face. A review was made on how to achieve realistic facial animation, focusing on the applications and limitations of the FACS comparing to MPEG-4 facial animation. The review inferred that FACS helps animators to represent and build realistic facial expressions by defining all conceivable facial liveliness units of the human face.
