Back to the Future: Joint Aware Temporal Deep Learning 3D Human Pose Estimation

22 Feb 2020vnmr/JointVideoPose3D

We propose a new deep learning network that introduces a deeper CNN channel filter and constraints as losses to reduce joint position and motion errors for 3D video human body pose estimation.
