We introduce the SCAPE method (Shape Completion and Animation
for PEople)a data-driven method for building a human shape
model that spans variation in both subject shape and pose. The
method is based on a representation that incorporates both articulated
and non-rigid deformations. We learn a pose deformation
model that derives the non-rigid surface deformation as a function
of the pose of the articulated skeleton. We also learn a separate
model of variation based on body shape. Our two models can be
combined to produce 3D surface models with realistic muscle deformation
for different people in different poses, when neither appear
in the training set. We show how the model can be used for shape
completion generating a complete surface mesh given a limited
set of markers specifying the target shape. We present applications
of shape completion to partial view completion and motion capture
animation. In particular, our method is capable of constructing a
high-quality animated surface model of a moving person, with realistic
muscle deformation, using just a single static scan and a marker
motion capture sequence of the person.
