What is Facial Recognition Technology?

Facial recognization technology refers to a type of software that helps to identify or verify a person by comparing and analyzing patterns based on the person’s facial formations. Facial recognization technology within its record matches a human face against photos and videos from the database.

People generally leverage this technology to authenticate users through ID verification services, as it is a category of biometric security. Besides the face, biometric software also includes voice recognition, fingerprint recognition, and eye retina or iris recognition.

However, facial recognition is considered the most natural method among all biometric measurements.

How Does Face Recognition Work?

If you are planning to develop a ai app, then it is essential for you to know how face recognition software works. In addition, this will help you connect more with your users as you will be able to understand their requirements and identify the opportunities and loopholes in the process.

How Face Recognition Works

  1. Capture

    First of all, the face recognition app captures the person’s face from images, videos, or in real-time. Then, the program finds the features of the face and determines the reference points.

    Earlier, only the eyes used to be the main reference point. However, now there are more than 70 key features to identify a person through his face.

  2. Extraction

    Further, it extracts the needed data from the image to identify a person. Now the features describing a person’s face are calculated, such as the age, hairstyle, eyes, and so on.

    The app reads the geometry of the face. In short, the app will create a digital portrait of the face with essential features and a face vector for further comparison.

  3. Comparison

    At this stage, the app compares the captured digital face vector with all the objects stored in the database. In short, the app treats your faceprint as a numerical code. In the same way, the thumbprint for each person is different; faceprint is also unique for everyone.

    This comparison stage could be a time taking process as the face will be compared with millions of objects to identify a person based on their facial features.

  4. Matching

    In the final stage, the faceprint is compared against a million objects. For example, if you are on Facebook, then any photo tagged with a person’s name becomes a part of the Facebook database.

    This may later be used to identify a person’s face by comparing it against a database of millions of faces. Later, the app decides whether your faceprint matches an image or not for the final identification of the person.

You get clarity on how your facial recognition app will work. Now, we will discuss the top face recognition apps. This is for your reference, so you know which apps are doing exceptionally well in this face recognition mobile app industry and what features they offer your target audience. Ultimately, this will help you discover the opportunities for your own project.
