This is how Facial Recognition works

Facial recognition is a way of recognizing a human face through technology. A facial recognition system uses biometrics to map facial features from a photograph or video. It compares the information with a database of known faces to find a match. Facial recognition can help verify personal identity, but it also raises privacy issues.

The facial recognition market is expected to grow to $7.7 billion in 2022 from $4 billion in 2017. That’s because facial recognition has all kinds of commercial applications. It can be used for everything from surveillance to marketing.

How facial Recognition Works;
Technologies adopted may vary, but here are the basic steps:

Step 1. A picture of your face is captured from a photo or video. Your face might appear alone or in a crowd. The image has to show you looking straight ahead or nearly.

Step 2. Facial recognition software reads the geometry of your face. Key factors include the distance between your eyes and the distance from forehead to chin. The software identifies facial landmarks that are key to distinguishing your face and this makes up your Facial Signature.

Step 3. Your facial signature — a mathematical formula — is compared to a database of known faces.

Step 4. A determination is made. Your faceprint may match that of an image in a facial recognition system database.

That basically is how A Facial Recognition Works.
