:triangular_flag_on_post: Updates

:white_check_mark: 2022.10.16 Clean research codes & Update VQFR-v2. In this version, we emphasize the restoration quality of the texture branch and balance fidelity with user control. <a href="https://colab.research.google.com/drive/1Nd_PUrHaYmeEAOF5f_Zi0VuOxlJ62gLr?usp=sharing"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="google colab logo"></a>
:white_check_mark: Support enhancing non-face regions (background) with Real-ESRGAN.
:white_check_mark: The Colab Demo of VQFR is created.
:white_check_mark: The training/inference codes and pretrained models in paper are released.

This paper aims at investigating the potential and limitation of Vector-Quantized (VQ) dictionary for blind face restoration. <br> We propose a new framework VQFR – incoporating the Vector-Quantized Dictionary and the Parallel Decoder. Compare with previous arts, VQFR produces more realistic facial details and keep the comparable fidelity.

:computer: Training

We provide the training codes for VQFR (used in our paper).

Dataset preparation: FFHQ
Download lpips weights [Google Drive] into experiments/pretrained_models/

Codebook Training

Pre-train VQ codebook on FFHQ datasets.

 python -m torch.distributed.launch --nproc_per_node=8 --master_port=2022 vqfr/train.py -opt options/train/VQGAN/train_vqgan_v1_B16_800K.yml --launcher pytorch

Or download our pretrained VQ codebook Google Drive and put them in the experiments/pretrained_models folder.

Restoration Training

Modify the configuration file options/train/VQFR/train_vqfr_v1_B16_200K.yml accordingly.
Training

python -m torch.distributed.launch --nproc_per_node=8 --master_port=2022 vqfr/train.py -opt options/train/VQFR/train_vqfr_v1_B16_200K.yml --launcher pytorch

:straight_ruler: Evaluation

We evaluate VQFR on one synthetic dataset CelebA-Test, and three real-world datasets LFW-Test, CelebChild and Webphoto-Test. For reproduce our evaluation results, you need to perform the following steps:

Download testing datasets (or VQFR results) by the following links:

<table> <tr> <th>Name</th> <th>Datasets</th> <th>Short Description</th> <th>Download</th> <th>VQFR Results</th> </tr> <tr> <td rowspan="5">Testing Datasets</td> <td>CelebA-Test(LQ/HQ)</td> <td><sub>3000 (LQ, HQ) synthetic images for testing</sub></td> <td rowspan="4"><a href="https://drive.google.com/drive/folders/1CPdaCijkhl8ojg9ZDCPXntQrnw-8tUeD?usp=sharing">Google Drive</a> </td> <td rowspan="4"><a href="https://drive.google.com/drive/folders/1w-qo5BsKBzSmE0hwS9Hl5G9fn4VKVweU?usp=sharing">Google Drive</a> </td> </tr> <tr> <td>LFW-Test(LQ)</td> <td><sub>1711 real-world images for testing</sub></td> </tr> <tr> <td>CelebChild(LQ)</td> <td><sub>180 real-world images for testing</sub></td> </tr> <tr> <td>Webphoto-Test(LQ)</td> <td><sub>469 real-world images for testing</sub></td> </tr> </table>

Install related package and download pretrained models for different metrics:

    # LPIPS
    pip install lpips

    # Deg.
    cd metric_paper/
    git clone https://github.com/ronghuaiyang/arcface-pytorch.git
    mv arcface-pytorch/ arcface/
    rm arcface/config/__init__.py arcface/models/__init__.py

    # put pretrained models of different metrics to "experiments/pretrained_models/metric_weights/"

<table> <tr> <th>Metrics</th> <th>Pretrained Weights</th> <th>Download</th> </tr> <tr> <td>FID</td> <td>inception_FFHQ_512.pth</td> <td rowspan="3"><a href="https://drive.google.com/drive/folders/1k3RCSliF6PsujCMIdCD1hNM63EozlDIZ?usp=sharing">Google Drive</a> </td> </tr> <tr> <td>Deg</td> <td>resnet18_110.pth</td> </tr> <tr> <td>LMD</td> <td>alignment_WFLW_4HG.pth</td> </tr> </table>

Generate restoration results:

Specify the dataset_lq/dataset_gt to the testing dataset root in test_vqfr_v1.yml.
Then run the following command:

    python vqfr/test.py -opt options/test/VQFR/test_vqfr_v1.yml

Run evaluation:

    # LPIPS|PSNR/SSIM|LMD|Deg.
    python metric_paper/[calculate_lpips.py|calculate_psnr_ssim.py|calculate_landmark_distance.py|calculate_cos_dist.py]
    -restored_folder folder_to_results -gt_folder folder_to_gt

    # FID|NIQE
    python metric_paper/[calculate_fid_folder.py|calculate_niqe.py] -restored_folder folder_to_results
