This is a pretty bad documented and totally unmaintained face alignment project.
Build (compiling Dlib and OpenCV takes ages, be patient) and run a bash into the container:
docker build -t face .
docker run -ti -v $(pwd)/:/home face /bin/bash
Calling the API:
#from a path of jpg's creates a an average target.jpg
face_average(path, target)
#from a path of jpg's creates an image sequence blending pairs
face_morph(path, target)
