A 3D facial expression animation system based on MPEG-4
Wang Zeng-fu · 2011
In view of the model based coding/decoding area,a 3D facial expression animation system based on MPEG-4 was proposed.The coder obtained FDPs(facial definition parameter) through face adaptation of a simple universal triangular model with Adaboost + Camshift + AAM algorithm for face detection and feature localization in the first frame.Then the decoder adapted a complex universal triangular model using these FDPs,Finally the algorithm produced facial animation combining the parameterized model and muscle model.A facial action area split scheme was also proposed.Experiment results confirm that this system can produce realistic facial expression animation with FAP(facial animation parameter) flow.
