Script that will detect if a stranger is trying to use your laptop or if a stranger/authorized driver is trying to drive your car. This script will detect the face, and send you an email if new user is not identified.
A face detector (not facial identification) deep learning system based upon OpenCV and Tensorflow. Optimized for CPU, not GPU operation but does have a tensorflow-gpu switch available. Can even identify faces that aren't edge-on or partially obscured.
A study of how to use hair and facepaint to interfere with facial recognition and surveillance software May be useful in the event that wearing masks is infeasible.
How to build a facial recognition system using the TrueFace API and images stored in Dropbox.
