What is the principle of face recognition technology now?

Only four steps are needed to understand the working principle of the face recognition module.

Before studying the edge face recognition and its application, let's discuss the working principle of the face recognition module.

Face recognition technology can identify or verify the identity of individuals by analyzing faces. Face recognition artificial intelligence runs by matching the face captured by the camera with the pre-recorded face database.

Although there are many types of face recognition systems, they usually work in the following ways:

Step 1: Face detection and face recognition.

The camera locates and recognizes clear facial images. When individuals are alone or in a group, faces can be recognized.

In addition, face detection can identify people on the front or side, so the camera can only capture their personal data.

Step 2: Face analysis measures the face.

Analyze the image by reading the mapping way of the face.

Artificial intelligence software will analyze and measure the distance from forehead to chin and the distance between eyes. It also determines the shape of the ears, lips, chin and cheekbones. The purpose is to identify the key features of your face, which determine who you are.

Step 3: Convert the shot image into data.

According to all the collected measurement results, the face classified as analog information is converted into data and classified as digital information. The face is now converted into a mathematical formula and has its own digital code called facial texture. Facial fingerprints are like fingerprints. No two are the same.

Step 4: Face Matching Compare your face with the database.

Personal facial fingerprints are now in the database and can be compared with all other facial fingerprints. When a person's facial fingerprint matches another image in the facial recognition database, a person will be given an identity.
