Abstract EN
We introduce a novel parameterization of facial expressions by using elastic surface model.
The elastic surface model has been used as a deformation tool especially for nonrigid organic objects.
The parameter of expressions is either retrieved from existing articulated face models or obtained indirectly by manipulating facial muscles.
The obtained parameter can be applied on target face models dissimilar to the source model to create novel expressions.
Due to the limited number of control points, the animation data created using the parameterization require less storage size without affecting the range of deformation it provides.
The proposed method can be utilized in many ways: (1) creating a novel facial expression from scratch, (2) parameterizing existing articulation data, (3) parameterizing indirectly by muscle construction, and (4) providing a new animation data format which requires less storage.
