Liveness

Estimate score for eyes blink. Score indicates likelihood of eye being open (0 is closed, 1 is open). Optimal threshold is 0.4 in normal use and 0.1 in low light conditions

Use the following guidelines for best performance:

  • Camera should see frontal view of the face

  • The eyes should be looking directly into the camera

  • The face should be 1 - 2 ft from the camera

  • Recommended 640 x 480 resolution or better

  • Ensure there is good lighting illuminating the eyes
