What is facial recognition? Facial recognition is a biometric technology designed to identify or verify individuals based on their unique facial characteristics. Technically, it works by analyzing and comparing patterns of facial features extracted from images or video frames. These patterns include measurements between key facial landmarks such as the eyes, nose, and mouth, as well as the overall shape and contours of the face.
Simply put, facial recognition mimics the human ability to recognize faces in a crowd, for example. Using algorithms, this technology examines and identifies specific features unique to each person, providing computers with the capability to "see" and recognize faces with the speed and precision of machine learning.
Facial recognition has a wide range of applications and the most popular use case is lock screen technology for smartphones. A glance at your phone can unlock it instantly, eliminating the need to enter a passcode or remember a pattern. Setting up facial recognition on a smartphone involves teaching the device to recognize your face. The phone camera captures a series of images during registration, collecting different viewpoints and expressions to create a digital blueprint of your facial features.
When you attempt to unlock your phone, the front-facing camera activates and scans your face, noting critical features such as the distance between your eyes, the shape of your nose, and the angles of your jaw. It compares these features with the stored blueprint. If there is a match within a tiny margin of error, the phone unlocks instantly.
Thus, whether unlocking a smartphone or identifying individuals in surveillance footage, facial recognition technology relies on analyzing and matching unique facial features against stored data.
