Obtaining MPEG-4 Facial Animation Parameter Based on Marked Images
Wen Gao · Acta Simulata Systematica Sinica · 2001
In this paper we put forward a method through which we can obtain the MPEG-4 FAP (Facial Animation Parameter). Firstly, we put some marks on the human face according to the MPEG-4 FDP (Face definition parameter), then we record the video sequence of the face movement and voice data. By segmenting and locating the marked points in the images, we extract location of the feature points marked on the human face and then confirm them according to the pre-known knowledge of feature points location of human faces. Finally we get the FAP (Facial Animation parameter). We obtained very good result when the result data was applied to the synthesis and animation of human faces.
