Description

Is it possible to detect if the face in front of the camera is blinking his/her eyes? This will really help to mitigate simple loopholes like using a life-size image of a person, especially when camera lacks IR.

Research direction
The issue requests eye blink detection to prevent spoofing. Research the current Howdy face detection pipeline, likely using dlib's face landmark detector to extract eye landmarks. Implement the Eye Aspect Ratio (EAR) metric to detect blinks in a real time video stream. Refer to files like 'howdy/src/face.py' or similar for integration points. Consider adding a check before authentication to ensure the user blinks within a short window.
