The Keras CNN provided in the DHP19 reference code estimates the 13 joint positions.
Each video shows the ground truth (red) and 3D pose estimation (blue) based on the two cameras facing the front of the subject.
The joint estimation is good for moving parts of the bodies. For immobile parts, large outliers are sometimes produced. See the paper for discussion.
