Request Body
Input Example in Postman
Interpretation of Result
Probability of liveness is a main response of the system.
The image is accepted as "live" when a probability is bigger than 0.5.
Linear liveness score can be used for BPCER / APCER tuning.
The range of score is (ln 1e-7, -ln 1e-7).
Quality value is a probability of "appropriate image".
Probability can be lower than 0.5 by the reasons below.
Face minimal side is less than 180 pix or distance between eyes is less than 90 pix.
Face out-of-plane rotation is bigger than 20 degrees.
The distance between face and camera is very small, so the face can be significantly distorted.
The luminous power is insufficient.
High motion or gaussian blur rate or light shot.
We highly advise to analyze quality value and reject inappropriate images.
