OSSO: Obtaining Skeletal Shape from Outside (CVPR 2022)

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

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

News 15/02/2024: Check out our new skeleton model SKEL (Siggraph Asia 2023). SKEL as similar features as OSSO but the skin is rigged with the skeleton and the skeleton can be reposed.

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

Installation

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

Run skeleton inference

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.

To export the skeleton mesh as separated meshes, add the --per_part option to the previous command.

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.
