The Application of Independent Component Analysis in MPEG-4 Based Facial Animation

To gain the realistic MPEG-4 facial animation, Independent Component Analysis (ICA) is applied to the pattern extraction of facial animation parameters (FAPs). By studying the independent sources and their project on human expression, some steady independent components are extracted to come into being. Experiment results show that MPEG-4 facial animation based on ICA space is more robust and more realistic.
