摘要：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.
