What camera angles are required for recognition?

Although the ideal angle is for subjects to be looking straight at the camera, SAFR can recognize faces that deviate from the ideal angle by quite a bit. Even subjects in a 90° profile pose can be matched against a database of identities, though with a reduced accuracy. The best recognition attempts generally occur at angles of -30° to +20°  pitch (down/up), -40° to +40° yaw (left/right), and -10° to +10° roll.
