With the progress of our society, science and technology continue to innovate, and technology continues to iterate according to user needs. As the most popular identification technology at the moment, face recognition in biometrics is not unfamiliar to everyone. Pay with face, authentication, pass, and climb stairs, etc., to make people's lives more efficient, smart, and faster.

According to the forecast of the Foresight Industry Research Institute, by 2021, the face recognition market will reach about 5.1 billion yuan. Based on the updated iteration of face access control recognition system technology, there will be broader development space in security fields such as prisons, vehicle supervision, border inspection, courts, and transportation.

At present, most companies in my country use face recognition technology as one of the standard technologies. According to the changes in market demand, many interesting and intelligent products have been developed. So what role does face recognition play in the field of security?

Face recognition technology has two main types of applications in the security field:

Static face recognition

Static face recognition refers to a person’s identity search and identity management by comparing a static face photo with a face database.

What are the main applications of this type of system?

Generally speaking, in terms of public security and household registration management, the current static face matching recognition technology is relatively mature. This is because the main source of the database is the ID photos, and the photos are mainly the front poses of human faces. The image quality is usually better. Therefore, the current state of the art algorithm can already meet the recognition results.

Dynamic face monitoring and recognition

Dynamic face monitoring and recognition The face recognition system based on the video surveillance system can directly process the face images in the real-time video stream for face monitoring.

From an application point of view, real-time dynamic face recognition can be applied to a variety of scenarios to meet a variety of needs. At present, the most common one is through the face monitoring and recognition system of the target person (including black/white list) and the field of vision through the camera. Compare the face with the black/white list, determine whether it belongs to the list, and further determine its authority. According to the current technical level, the library capacity of the list can generally reach hundreds of thousands of orders of magnitude.
