SCARF: Capturing and Animation of Body and Clothing from Monocular Video

This is the Pytorch implementation of SCARF. More details please check our Project page.

SCARF extracts a 3D clothed avatar from a monocular video.
SCARF allows us to synthesize new views of the reconstructed avatar, and to animate the avatar with SMPL-X identity shape and pose control. The disentanglement of thebody and clothing further enables us to transfer clothing between subjects for virtual try-on applications.

The key features:

1. animate the avatar by changing body poses (including hand articulation and facial expressions),
2. synthesize novel views of the avatar, and
3. transfer clothing between avatars for virtual try-on applications.

Getting Started

Clone the repo:

git clone https://github.com/yfeng95/SCARF
cd SCARF

Requirements

conda create -n scarf python=3.9
conda activate scarf
pip install -r requirements.txt

If you have problems when installing pytorch3d, please follow their instructions.

Download data

bash fetch_data.sh

Visualization

• check training frames:

python main_demo.py --vis_type capture --frame_id 0 

• novel view synthesis of given frame id:

python main_demo.py --vis_type novel_view --frame_id 0 

• extract mesh and visualize

python main_demo.py --vis_type extract_mesh --frame_id 0

You can go to our project page and play with the extracted meshes.

• animation

python main_demo.py --vis_type animate

• clothing transfer

# apply clothing from other model 
python main_demo.py --vis_type novel_view --clothing_model_path exps/snapshot/male-3-casual
# transfer clothing to new body
python main_demo.py --vis_type novel_view --body_model_path exps/snapshot/male-3-casual

More data and trained models can be found here, you can download and put them into ./exps.

Training

• training with SCARF video example

bash train.sh

• training with other videos
  check here to prepare data with your own videos, then change the data_cfg accordingly.

TODO

• add more processed data and trained models
• code for refining the pose of trained models
• with instant ngp
