Problem with anthropometric data
They all need to be licensed
A good start to this would be
check out the SMPL* body models first
they have provided starter code for use with neural network libraries such as tensorflow/pytorch
This blog post describes how to use the code related to these models
Overview of SMPL* models and methods
This is from one of their youtube videos :
smplify-x
This computes a body model using a single photo
There is also PiFU-HD which does , but that is non-parametric
Consequently, we follow the approach of SMPLify, which estimates 2D features and then optimizes model parameters to fit the features.
they use 2d features to optimize SMPL-X model parameters
