Together with Ava-256, part of Codec Avatar Studio

We provide 4 sets of captures; for each subject:

• 1 relightable head capture
• 1 relightable hands capture
• 1 fully clothed capture
• 1 minimally clothed capture
• 1 mobile head capture
• 1 mobile hands capture
• 1 mobile fully clothed capture
• 1 mobile minimally clothed capture

And code to train personalized decoders:

• Relightable Gaussian Codec Avatar Heads (CVPR'24)
• Relightable hands (CVPR'23)
• Universal relightable hands (CVPR'24)
• Mesh-based bodies (ToG'21)

Please refer to the samples to get a sense of what the data looks like.

Disclaimer

This is a pre-release.

Dependencies

See requirements.txt/environment.yaml

Repository structure

• ca_code/ - python source

  • loss - loss functions
  • models - standalone models
  • nn - reusable modules (layers, blocks, learnable, modules, networks)
  • utils - reusable utils (functions, modules w/o learnable params)

• notebooks/ - example notebooks

• extensions/ - CUDA extensions

• data/ - location of sample data and checkpoints

Data

Besides camera, views, we also provide segmentations, 3d keypoints, registered and unregistered meshes, as well as light information when available.

goliath_assets.mp4

Access to the dataset is currently gated. Please email [email protected], preferrably from an institutional email, to get access to the data.

Compiling and installing extensions

cd extensions/{mvpraymarch,sgutils,utils}
make

Training

(You may have to add the directory of the codebase to your PYTHONPATH)

python ca_code/scripts/run_train.py <config.yml>

or simply

python -m ca_code.scripts.run_train <config.yml>

(URHand training) You may need to unwrap images to get color_mean.png for static hand assets before launch training in case there is no color_mean.png under uv_images for the target identity:

python -m ca_code.scripts.run_gen_texmean config/urhand_mesh_example.yml

Visualization (Relighting)

python ca_code/scripts/run_vis_relight.py <config.yml>
