What is Face Recognition?
Face recognition is a technique for identifying or verifying the identity of a person based on his/her face. This system can recognize human faces in images or videos, judge whether a face appears in two images of the same person, or search for a face among many existing images. Facial recognition is a technique used by biometric security systems to more reliably identify users during the registration or login process. Facial analysis technology is also widely used in mobile and personal devices to ensure device security.
How does Face Recognition work?
In addition to unlocking phones, face recognition uses sophisticated cameras to compare the faces of passersby with images of people on a pre-defined list. The photos on the pre-defined lists can come from anywhere, including our social media accounts, and they can be of anyone, including those who aren't suspected of a crime. Although facial recognition systems can vary, they typically work as follows
Detection
Locating a face in a picture is the process of face recognition online. Computer vision makes face detection and identification from an image, including one or more people's faces, possible. Both front and side face profiles with facial data can be detected. Through computer vision, computers can now recognize individuals, locations, and objects in photos with accuracy comparable with or better than that of humans and at a considerably faster rate. Computer vision automates the extraction, analysis, classification, and understanding of useful information from image editing data using sophisticated artificial intelligence (AI) technology.
Analysis
The face is then captured and evaluated in the next step. Most facial recognition technology uses 2D rather than 3D photos because matching a 2D image to existing data or public photos is faster. The computer analyzes the geometry of your face. The distance between your eyes, the depth of your eye sockets, the distance between your forehead and chin, the shape of your cheekbones, and the shape of your lips, ears, and chin are all important considerations. The goal is to identify the distinctive features that make your face unique.
Recognition
Facial recognition can identify a person by comparing the faces in two or more photographs and determining the probability that two faces match. For example, it can confirm that the face in a selfie taken with a mobile device matches the face in an image of a government-issued ID, such as a driver's license or passport, and confirm that the face in the selfie does not match a face in a collection of previously photographed faces.
Facial Recognition using Saiwa Online Demo
