High-Fidelity Clothed Avatar Reconstruction from a Single Image

Paper

This repository contains the official PyTorch implementation of:

High-Fidelity Clothed Avatar Reconstruction from a Single Image

Table of Contents

Installation

  • CUDA=10.2
  • Python = 3.7
  • PyTorch = 1.6.0

1. Setup virtual environment:

conda create -n car python=3.7
conda activate car

# install pytorch
conda install -c pytorch pytorch=1.10.0 torchvision==0.7.0 cudatoolkit=10.2

# install pytorch3d 
pip install pytorch3d -f https://dl.fbaipublicfiles.com/pytorch3d/packaging/wheels/py37_cu102_pyt1100/download.html

# install trimesh  
conda install -c conda-forge rtree pyembree
pip install trimesh[all]

# install other dependencies
pip install -r requirement.txt

# install customized smpl code
cd smpl
python setup.py install
cd ../

If you use other python and cuda versions (default python3.7 cuda 10.2), please change the cuda version and python version in ./install.sh. If you use other pytorch version (default pytorch 1.6.0), please install pytorch3d according to the official install instruction official INSTALL.md.

2. Download smpl models from https://smpl.is.tue.mpg.de/, put them into models folder under ./data/smpl_related/models/smpl/

Training

# CAR 
python -m apps.train -cfg configs/car-rp.yaml --gpu 0 

# ARCH* (*: re-implementation)
python -m apps.train -cfg configs/arch.yaml --gpu 0

The results will be saved in ./out/.

Inference

  • Download the pretrained models and put it in ./out/ckpt/ours-normal-1view/.
  • Download extra data (PyMAF, ICON normal model, SMPL model) and put them to ./data.
  • Run the following script to test example images in directory ./examples. Results will be saved in ./examples/results.
python -m apps.infer --gpu 0 -cfg configs/car-rp.yaml
