In this article, we’ll go over more about how facial recognition technology works so that you can decide if it’s right for your needs.
The basic steps of digital facial recognition can be broken down like this:
- A picture of someone’s face is captured, either via a still photo or a video. This picture might show the individual alone or in a crowd, with their face towards the camera or in profile. The software will still be able to analyze the image.
- The facial recognition software then scans the geometry of the face, identifying key “facial landmarks” that distinguish one face from another, such as the distance between the eyes, length of the nose, etc. Depending on the specific program, as many as 68 of these landmarks can be used to analyze a face and generate a string of data known as the facial signature.
- Once the software has calculated the facial signature, it will compare it against one or more databases of known faces, such as those maintained by various police departments or federal agencies. According to experts, as many as 117 million Americans appear in one or more police databases, giving facial recognition technology a large pool of data to work with.
- Finally, the program makes a determination, matching the face in the image captured at your business to one in the database.
