Thanks for the feedback!
Developing the face recognition system is out of scope for this project, the main aim of this project is creating new face detection/recognition databases by programmatically!
In this project, Adam Geitgey’s face recognition system (thanks a lot to Adam) was used for face recognition and it can be installed by pypi using pip3 (or pip2 for Python 2):
pip3 install face_recognition
This information was added on the project [GitHub](https://github.com/ahmetozlu/face_recognition_crop) repository too!
