Facial recognition explained

Facial recognition is a solution based on AI algorithms for face detection and recognition. The systems measure an individual’s eye shape, forehead length, and nose parameters, matching them with the biometrics previously obtained from individuals. If a face recognition engine finds a match in a database, it confirms a person’s identity. Face matching can be done in real-time or through images and video.

The technology has proven efficient in face analysis aimed at recognizing individual’s characteristics including gender, age, emotions, movements, mood, and face mask detection that helps notice people who are violating the rules of wearing a mask in public places amidst the coronavirus pandemic.

Unlike such authentication means as passwords, emails, and fingerprints, biometric facial identification applies unique dynamic patterns and mathematical equations that ensure the safety and efficiency of a face detection system.

Face identification technologies are currently experiencing large-scale application across different spheres, including retail and e-Commerce, media and entertainment, automobile and transportation, telecom and IT, government, health, and others. Now let’s see how the face identification system operates.

Main steps in facial recognition technology

Facial recognition is far and away a monumental breakthrough in biometric technologies. Wherever and whenever a person sees a face, AI facial recognition technology perceives it as data. This data is processed to authenticate an individual’s identity through the following steps.

steps-in-facial-recognition-technology

Step 1. Detecting a face

It is the primary stage facial recognition systems execute to detect a face. The detection process involves scanning the image to determine whether any area has full human faces or partial features. This step is crucial to the entire process as the technology must catch a face alone or among other people quickly and precisely.

Step 2. Extracting facial features

Facial recognition software analyzes a person’s facial geometry (eye space, eyebrows, nose bridge, lip contour, forehead and chin, ears, and the shape of cheekbones). To be exact, the solution can identify almost 70 facial landmarks. Having extracted these traits, the engine creates a template of the face contrasting it to those in the database.

Step 3. Recognizing a face

This stage involves procedures of verification and identification. Verification is done when it is necessary to authenticate a person’s identity. For this purpose, the facial recognition system will conduct a face match using a faceprint obtained during the previous step. This procedure proves whether or not a person is the one they claim to be by evaluating two faceprints.

As a result, the system obtains a single score value demonstrating similarities between these two faces. For example, you go through the face verification process while unlocking your mobile phone or logging into the portal of financial services for mobile banking.

The second procedure aims to identify a person saying who they are. This time the engine will search the database of previously enrolled faces for a perfect match of an individual’s Faceprint.
