Facial recognition systems are capable of identifying or verifying a person from a digital image or a video source. There are multiple methods in which facial recognition systems work, but in general, they work by comparing selected facial features from given image with faces within a database. It is also described as a biometric artificial intelligence based application that can uniquely identify a person by analyzing patterns based on the person's facial textures and shape. It has seen wider uses in recent times on mobile platforms, for access control, public safety, and as a payment method. Facial recognition can be compared to other biometrics such as fingerprint or eye iris recognition systems.
