This example demonstrates a very simple facial landmark detection using Dlib's machine learning algorithms, using depth data to implement basic anti-spoofing.
Faces detected by the camera will show landmarks in either green or red:
Green landmarks indicate a "real" face with depth data corroborating expectations. E.g., the distance to the eyes should be greater than to the tip of the nose, etc.
Red landmarks indicate a "fake" face. E.g., a picture of a face, where the distance to each facial feature does not meet expectations
