This repository contains the official implementation of the skeleton inference from:

OSSO: Obtaining Skeletal Shape from Outside
Marilyn Keller, Silvia Zuffi, Michael J. Black and Sergi Pujades
Full paper | Project website

Given a body shape with SMPL or STAR topology (in blue), we infer the underlying skeleton (in yellow).

Please follow the installation instruction in installation.md to setup all the required packages and models.

The skeleton can be inferred either from a SMPL or STAR mesh.

python main.py  --mesh_input data/demo/body_female.ply --gender female -D -v

The final infered skeleton will be saved in the out folder and the intermediate meshes in out/tmp.

OSSO uses the Stitched Puppet by Silvia Zuffi and Michael J. Black, and the body model STAR by Ahmed Osman et al. The model was applied on AGORA (Priyanka Patel et al.) for demonstration.

This research has been conducted using the UK Biobank Resource under the Approved Project ID 51951.

We thank Anatoscope (www.anatoscope.com) for the initial skeleton mesh and useful discussions.

We also thank A. A. Osman for his helpful advice on body models, P. Patel for helping test OSSO on AGORA, T. McConnel, Y. Xiu, S. Tripathi and T. Yin for helping with the submission and release, and P. Ghosh, J. Tesch, A. Chandrasekaran, V. F. Abrevaya, S. Sanyal, O. Ben-Dov and P. Forte for fruitful discussions, advice and proofreading.
