Detects a masked face

Until now, Vision could detect faces, but could not detect faces with masks.

Conventionally, the face of the mask is not detected

I took it in the wrong direction and detected that the mask was not worn (the fact that Vision reacts does not mean that the mask is not worn).

Implementing the app that detects people without a mask with Vision (Apple official framework)

Starting with the 2021 iOS 15 version, masked faces can also be detected.

The minimum configuration to detect a face is as follows.

The masked face can be detected from VNDetectFaceRectanglesRequestRevision3.
