Overview of our proposed method. It mainly contains two parts: (a) the off-line generation of multi-scale component dictionaries from large amounts of high-quality images, which have diverse poses and expressions. K-means is adopted to generate K clusters for each component (i.e., left/right eyes, nose and mouth) on different feature scales. (b) The restoration process and dictionary feature transfer (DFT) block that are utilized to provide the reference details in a progressive manner. Here, DFT-i block takes the Scale-i component dictionaries for reference in the same feature level.

(a) Offline generation of multi-scale component dictionaries.

(b) Architecture of our DFDNet for dictionary feature transfer.

• Pytorch (≥1.1 is recommended)

1. Crop face from the whole image.

cd ./CropFace
python crop_face_dlib.py

2. Compute the facial landmarks.

cd ./FaceLandmarkDetection
python get_face_landmark.py

3. Run the face restoration.

python test_FaceDict.py
