Abstract
In this paper, we present a novel strategy to design disentangled 3D face shape representation. Specifically, a
given 3D face shape is decomposed into identity part and
expression part, which are both encoded in a nonlinear
way. To solve this problem, we propose an attribute decomposition framework for 3D face mesh. To better represent face shapes which are usually nonlinear deformed between each other, the face shapes are represented by a vertex based deformation representation rather than Euclidean
coordinates. The experimental results demonstrate that our
method has better performance than existing methods on
decomposing the identity and expression parts. Moreover,
more natural expression transfer results can be achieved
with our method than existing methods.
