This post mainly covers following works in brief:
SMPL (Skinned Multi-Person Linear Model)#
Trained parameters of an SMPL default body are as follows:
- T ==> Mesh Vertices
- W ==> Blending Weights
- S ==> Shape Displacement Vectors
- P ==> Pose Displacement Vectors
- J ==> Joint Transformation Matrix
Given two parameters, $\theta$ for pose of human body and $\beta$ for shape of a subject, default human body is transformed to subject’s geometric characteristics and a particular pose as encoded by $\theta$
