Facial recognition system

Facial recognition is a technology that can help a computer to recognize a person's face. It works by first scanning a person's face with a camera and then analyzing the data to create a unique image of the person. It compares this unique image to a collection of other images stored in a database, to try and match the face with the same person. If it finds a match, then it can provide information about who that person is. This technology is used in many places—from your phone unlocking to airport security.
