📢 News

  • 12/11/2022 We released an OpenGraphAU or OpenGraphAU version of our code and models trained on a large-scale hybrid dataset of over 2,000k images and 41 action unit categories.

Learning Multi-dimensional Edge Feature-based AU Relation Graph for Facial Action Unit Recognition

This is an official release of the paper

"Learning Multi-dimensional Edge Feature-based AU Relation Graph for Facial Action Unit Recognition", IJCAI-ECAI 2022

[Paper] [Project]

The main novelty of the proposed approach in comparison to pre-defined AU graphs and deep learned facial display-specific graphs are illustrated in this figure.

🔧 Requirements

  • Python 3

  • PyTorch

  • Check the required python packages in requirements.txt.

pip install -r requirements.txt

Data and Data Prepareing Tools

The Datasets we used:

We provide tools for prepareing data in tool/. After Downloading raw data files, you can use these tools to process them, aligning with our protocals. More details have been described in tool/README.md.

Training with ImageNet pre-trained models

Make sure that you download the ImageNet pre-trained models to checkpoints/ (or you alter the checkpoint path setting in models/resnet.py or models/swin_transformer.py)

The download links of pre-trained models are in checkpoints/checkpoints.txt

Thanks to the offical Pytorch and Swin Transformer

Training and Testing

  • to train the first stage of our approach (ResNet-50) on BP4D Dataset, run:
python train_stage1.py --dataset BP4D --arc resnet50 --exp-name resnet50_first_stage -b 64 -lr 0.0001 --fold 1 
  • to train the second stage of our approach (ResNet-50) on BP4D Dataset, run:
python train_stage2.py --dataset BP4D --arc resnet50 --exp-name resnet50_second_stage  --resume results/resnet50_first_stage/bs_64_seed_0_lr_0.0001/xxxx_fold1.pth --fold 1 --lam 0.05
  • to train the first stage of our approach (Swin-B) on DISFA Dataset, run:
python train_stage1.py --dataset DISFA --arc swin_transformer_base --exp-name swin_transformer_base_first_stage -b 64 -lr 0.0001 --fold 2
  • to train the second stage of our approach (Swin-B) on DISFA Dataset, run:
python train_stage2.py --dataset DISFA --arc swin_transformer_base --exp-name swin_transformer_base_second_stage  --resume results/swin_transformer_base_first_stage/bs_64_seed_0_lr_0.0001/xxxx_fold2.pth -b 64 -lr 0.000001 --fold 2 --lam 0.01 
  • to test the performance on DISFA Dataset, run:
python test.py --dataset DISFA --arc swin_transformer_base --exp-name test_fold2  --resume results/swin_transformer_base_second_stage/bs_64_seed_0_lr_0.000001/xxxx_fold2.pth --fold 2
