What is Facial Recognition

Facial Recognition is an application on a computer that can identify or recognize a person from a digital image or video. Using an image of the subjects’ face, a facial recognition algorithm analyzes the face’s features and measures the distance of the face’s landmarks in relation towards each other. There are two ways facial recognition can be used: geometric, which analyzes distinguishing facial features, and photometric, which converts an image of a face into values that can be compared with a template image of the same subject for recognition. In addition to these two methods, skin texture analysis can be used to determine specific patterns, lines, and spots on the subject’s skin and a mathematical space is created to measure the size of each mark and the distance between them.
