+We use the deformable human model [**Adam**](http://www.cs.cmu.edu/~hanbyulj/totalcapture/) in this code.

+**The relationship between Adam and SMPL:** The body part of Adam is derived from [SMPL](http://smpl.is.tue.mpg.de/license_body) model. It follows SMPL's body joint hierarchy, but uses a different joint regressor. Adam does not contain the original SMPL model's shape and pose blendshapes, but uses its own version trained from Panoptic Studio database.
