(1) Time consuming for login: referring to the time consumed from test user sitting in front of camera to test user login successfully.
(2) Number of frames recognized: referring to the number of frames used to calculate the average credibility.
(3) —: referring to the immediate login.
(4) ∞: referring to the failure of login.
(5) The threshold value of credibility is set as 0.85.
