A Facial Expression Parameterization by Elastic Surface Model

Figure 2

The control points are a subset of MPEG-4 feature points (FPs) and some additional points. The total number is forty-seven for the test models. We put more control points around eyes and mouth since those facial parts need to be deformed more flexibly than other facial parts to make facial expressions.
