In order to determine someone's identity, facial recognition software compares newly captured images with images stored in a database. The core of the FaceIt facial recognition system is the Local Feature Analysis (LFA) algorithm. This is the mathematical technique used by the system when encoding holes. The system measures the facial hole and generates a facial pattern, which is a unique numerical code for the face.

Your face is an important element that identifies you, and others will also recognize you through your face. Imagine how difficult it would be to recognize a person if all faces were the same. Apart from twins who look almost identical, a face is undoubtedly the most unique physical feature of a person. Not only do humans have the innate ability to recognize and distinguish millions of different faces, but computers are also catching up with this ability.
