I did not state, that Apple uses steroscopic imaging, just an additional sensor beside the camera so the three dimensional shape of the face is also taken into account for the unlock process and not just the visual image of it. > What FaceID does is project a pattern onto the face and then measure the > positions to generate a depth map from a single POV sensor (therefore > not stereoscopic). Exactly. And this is more than just comparing an image, so you can not fool the system by just using an image of the owner in a flat medium in front of the camera. -- Arno Welzel https://arnowelzel.de
