Overview

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
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).

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.

AttributeError: 'add' object has no attribute 'v'

By some other algorithm, I got an ply file which is in smpl format. And I want to use your code to generate the skeleton. However, there is an error:

same topology as STAR or SMPL. Mesh has {skin_mesh.v.shape[0]} vertices, {sv.v.shape[0]} expected')
AttributeError: 'add' object has no attribute 'v'
``
Can you please tell me how can i use my own ply human surface to get the inside skeleton?
Thank you!

Can I directly generate bones with different poses and shapes by controlling shape parameters and pose parameters (like smpl)?

Thank you for your excellent work. Can I directly generate bones with different poses and shapes by controlling shape parameters and pose parameters (like smpl)? If so, is the shape parameter of the skeleton this? https://github.com/MarilynKeller/OSSO/blob/761e1abb87edb97ae80e1a68705d95b43ecd4865/osso/utils/inference.py#L31 Where are the posture parameters?

Psbody module Error

Hey, I have finished setting up the installation for the project but I am having trouble with the psbody mesh library and that's what I am getting: from psbody.mesh import Mesh, MeshViewer ModuleNotFoundError: No module named 'psbody'

When running the command "make all" everything is going smooth until it reaches the psbody module where it gives an error. Any help with that please?

Note that I am working on Windows 10 and I installed the Gnuwin32 and added it to path in order to use the 'make' command

use my own SMPL ply file get error

I use my image to genera a SMPL 3D model for inference as,

python main.py --mesh_input data/demo/img_hmr.obj --gender male -D -v

However, I got the error as follows,
