Abstract
A key disadvantage of blendshape animation is the labor-intensive task of sculpting blendshapes with
individual expressions for each character. In this paper, we propose a novel system ”Character Transfer”, that
automatically sculpts blendshapes with individual expressions by extracting them from training examples; this
extraction creates a mapping that drives the sculpting process. Comparing our approach with the naïve method of
transferring facial expressions from other characters, Character Transfer effectively sculpted blendshapes
without the need to create such unnecessary blendshapes for other characters. Character Transfer is applicable
even the training examples are limited to only a few number by using region segmentations of the face and the
blending of the mappings.
