Facial recognition uses deep learning algorithms to create positive IDs of individuals. Once face detection technology identifies a human face and captures the image, the image is transformed into a vector object (also called face signature), based on image landmarks. These are the position of both eyes, nose, and the two corners of the mouth relative to each other. Facial recognition works in tandem with a database in order for faces to be identified.
