Enhanced Blind Face Restoration with Multi-Exemplar Images and Adaptive Spatial Feature Fusion (CVPR 2020)

<h4>This is a re-implemented version of our ASFFNet by using:</h4>

• 512*512 images from CelebRef-HQ dataset of our DMDNet
• Degradation model from our ReDegNet

Prerequisites (I use python 3.8)

pip install -r requirements.txt

Pre-train Models

Download from the following url and put it into ./checkpoints/

• BaiduNetDisk or
• GoogleDrive

Testing

CUDA_VISIBLE_DEVICES=0 python main_test.py -s ./TestExamples/TestLists.txt -d ./TestExamples/TestResults

You may install the face_alignment by pip install face-alignment or conda install -c 1adrianb face_alignment

How to prepare the test data

1) Select the high-quality references (see ./TestExamples/ObamaRaw) and then crop face region using the following command:

cd TestExamples
CUDA_VISIBLE_DEVICES=0 python AlignAsFFHQ.py -s ./ObamaRaw -d ./HQReferences/Obama

2) Prepare the low-quality images (see ./TestExamples/LQRaw) and also crop face region using the following command:

cd TestExamples
CUDA_VISIBLE_DEVICES=0 python AlignAsFFHQ.py -s ./LQRaw -d ./LQCrop --no_padding

3) Detecting the facial landmarks of high-quality references by:

cd TestExamples
CUDA_VISIBLE_DEVICES=0 python FaceLandmarkDetection.py -s ./HQReferences

You can also add --check to show the face images labeled with the detected landmarks.

4) Preparing the TestLists.txt (see ./TestExamples/TestLists.txt) with the following format

'{}\t{}\t{}\n'.format([TEST_LQ_IMAGE_PATH],[ID_IMAGE_PATH],[ID_LANDMARKS_PATH])

5) Finally, running the following command for the guided face restoration

CUDA_VISIBLE_DEVICES=0 python main_test.py -s ./TestExamples/TestLists.txt -d ./TestExamples/TestResults

-s and -d represent the source and save pathes, respectively.

Some examples restored with different references on real-world low-quality images

From left to right: real-world low-quality input, high-quality reference, and restoration result

The first row for each group is restored with our selected optimal reference which is more consistent with the low-quality input (see poses and mouth open or closed). With our optimal reference, results are more photo-realistic and consistent with the identity (see the identity-belonging details in red boxes).
