Abstract

We propose a unified formulation for the problem of 3D human pose estimation from a single raw RGB image that reasons jointly about 2D joint estimation and 3D pose reconstruction to improve both tasks. We take an integrated approach that fuses probabilistic knowledge of 3D human pose with a multi-stage CNN architecture and uses the knowledge of plausible 3D landmark locations to refine the search for better 2D locations. The entire process is trained end-to-end, is extremely efficient and obtains stateof-the-art results on Human3.6M outperforming previous approaches both on 2D and 3D errors.

Dependencies

The code is compatible with python2.7

Models

For this demo, CPM's caffe-models trained on the MPI datasets (link) are used for 2D pose estimation, whereas for 3D pose estimation our probabilistic 3D pose model is trained on the Human3.6M dataset.

Testing

  • First, run setup.sh to retreive the trained models and to install the external utilities.
  • Run demo.py to evaluate the test image.
