Deformation transfer is to transfer the deformation of a source deforming model to a
target model. Not only the pose but the detailed deformations of a source model are
transferred to a target model, causing the characteristic deformations of the target model
are mixed with those of the source model. This leads to unnatural results. In this paper,
we present a novel example-based deformation transfer approach to solve this problem.
With the aid of a few target examples, the characteristic deformations of transferred target
models are recovered. We evaluate our approach with several full-body articulated
models. The experimental results show that our approach can generate more natural and
convincing deformation transfer results than other approaches.
