dense face landmark detection

dense-face-alignment

Most of the existing face-alignments detects the standard 68 face landmarks. However, there is a need of dense facial landmarks for tasks such 3d face reconstruction, face recognition etc. DAD-3DHeads proposed a dense 2d landmark detector based on 3D face reconstruction. However, their performance deteriorates when face is only a part of the image. see figure below. To improve on this, I used mediapipe facial detector to detect the face, use the detected face to DADNet and then project back the detected landmarks in the original image coordinate.

Dependencies

pip install -r requirements.txt

Note: if you are using mac silicon replace mediapipe with mediapipe-silicon in requirements.txt

How to replicate the results

python run.py -h

sample command

python run.py --data_path sample_input --num_points 445

sample command for custom points

python run.py --data_path sample_input --custom_index model_training/model/static/face_keypoints/ids1.npy
