Question: What is facial recognition and how does it work?

Facial recognition uses computer-generated filters to transform face images into numerical expressions that can be compared to determine their similarity. These filters are usually generated by using deep “learning,” which uses artificial neural networks to process data.

What does facial recognition look at?

A facial recognition system uses biometrics to map facial features from a photograph or video. It compares the information with a database of known faces to find a match. Facial recognition can help verify a persons identity, but it also raises privacy issues.

What can facial recognition be used for?

Facial recognition is used when issuing identity documents and, most often, combined with other biometric technologies such as fingerprints (preventing ID fraud and identity theft). Face match is used at border checks to compare the portrait on a digitized biometric passport with the holders face.

What is the process of face recognition?

Face recognition is often described as a process that first involves four steps; they are: face detection, face alignment, feature extraction, and finally face recognition. Face Detection. Locate one or more faces in the image and mark with a bounding box. Face Alignment.

Does Face ID work if you are asleep?

Face ID is even attention-aware. It recognizes if your eyes are open and your attention is directed towards the device. This makes it more difficult for someone to unlock your device without your knowledge (such as when you are sleeping). To use Face ID, you must set up a passcode on your device.
