What is Face Recognition?

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?

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.

Governments can use this technology to track criminals, but they can also track ordinary people at any time.

Room for error

Facial recognition data can contain errors that could lead to false accusations against innocent people. For example, a slight adjustment in camera position or a change in appearance, such as a new hairstyle, can lead to inaccuracies. According to a Newsweek investigation, 28 members of the U.S. Congress were misidentified by Amazon's facial recognition software in 2018.

Invasion of privacy

The most divisive issue is one of ethics and privacy. Governments have been known to store images of some people without their permission. The European Commission announced in 2020 that it is considering banning facial recognition technology in public areas for up to five years, to give time to develop a legal framework to prevent privacy and ethical breaches.

Massive data storage

Machine Learning as a Service is the foundation of facial recognition software, and for it to "learn" and produce reliable results, it requires massive amounts of data. These massive data sets require robust data storage. Small and medium-sized businesses may not have the tools to store the necessary data.

Applications and Use Cases of Face Recognition AI

Use Cases of Face Recognition
