Abstract:
One of the biggest drawbacks of Blendshape Animation is the enormous labor of sculpting its blendshapes with “expression individuality”. Expression individuality is diverse facial expression in which each of the characters’ facial expressions has on their own, other than its semantics. It was problematic for artists to sculpt blendshapes with unified expression individuality for every expression of the characters. Methods that generate coarsely sculpted blendshape, Deformation Transfer [Sumner et al. 2004] for instance, often yield artifacts which are caused by the individuality of each character’s facial expressions. Example-based Facial Rigging [Li et al 2010] was one of the solutions to supplement these artifacts, yet it was not effective when the numbers of training examples are limited.
In this paper, we propose a method to generate blendshapes with expression individuality with small number of training examples. Our system transfers expression individuality defined on training examples by defining it as mapping. By introducing region division and mapping blending, our method is applicable even the numbers of the training examples are limited with less artifacts.
