Available methods for synthesizing facial expressions synthesize basic expressions. Few methods synthesize subtle facial expressions such as a knavish smile or a cold smile. We developed a system for synthesizing subtle facial expressions. It uses an interactive interface based on a genetic algorithm. We use the five main parts of the face : eyebrows, eyes, mouth, and contours. These parts are deformed independently. Using this system, subtle facial expressions can be synthesized by iterating a deformation process for each part. Experiments showed that this system can efficiently synthesize subtle facial expressions.
