FacePad.computeDepthBasedScore Method

Module: FacePad

Definition

Computes the PAD score of a detected face using a depth map image.

A high score means a high probability for the face to be bona-fide, hence not an attack.

The minimum recommended value is 10.

Important

Loading the FaceDepthBasedPad2A model is required to use this function.
