Facial recognition technology is a way of recognizing the human face through technology. A facial recognition system uses biometrics to map facial features from a video. It compares the information with a database of known faces to find a match. You’re familiar with their facial features — their eyes, nose, mouth — and how they come together.
That’s how a facial recognition technology system works, but on a grand, algorithmic scale. Where you see a face recognition technology sees data. That data can be stored. For instance, half of all American adults have their images stored in one or more facial-recognition databases.
So how does facial recognition work? Technologies vary, but here are the basic steps:
face recognition technology identifies the unique features of the human face and them makes a comparison based on the existing database of photographs. Identifying the human face includes concentrating on certain unique features, such as the jaw, cheekbones, face shape and so on. Once the image in the database matches with the face of the person concerned, the face is verified.
The non-contact feature of this solution makes the identification and verification of a person’s identity much easier and involves less processing than any other identification system.
