What is the insensitivity of Apple 13 face recognition?

1, illumination problem: Although the current facial recognition technology is very mature, it is also affected by some external factors. When the user's environment is special and the light is bright or dark, the device will not be able to correctly identify the special features of the face.

At this time, if you use the facial recognition function to scan the face, it will be unrecognizable. It's not that there is something wrong with the face unlocking function, but that the mobile phone is locked and the scanned image is incorrect, so there will be no response. In this case, please change to a soft lighting environment, and then use this function to unlock normally.

2. Facial problems: There are many kinds of facial recognition technologies, some of which can distinguish whether the other person is himself or not according to some characteristics of people, but some facial recognition technologies are very elementary and cannot recognize too special characteristics. When my appearance and dress change, it will also lead to face recognition failure.

Such as makeup, makeup remover, bangs, glasses and so on. Will lead to face recognition failure. For example, in some big companies, in order to protect the safety of employees, a facial recognition security system is set at the door, and some women cannot be recognized by this security system without makeup. So try to restore the face to the state of "collecting face" and then use this function to unlock it.

3. Mobile phone failure: Although smart phones are easy to use, their systems are prone to errors. When the built-in facial recognition software of the mobile phone fails, this function will not work normally. Because the phone is locked, it is impossible to manually start or restart the screen locking software. The safest way is to unlock it with a password, then restart the phone, and the function will be automatically restored, and then unlock it with the face unlock function.
