Technical Characteristics of Face Recognition

The traditional face recognition technology is mainly based on visible light image face recognition, which is also a familiar recognition method, and has more than 30 years of research and development history.

However, this approach has insurmountable defects, especially when the environmental lighting changes, the recognition effect will be sharply reduced, and can not meet the needs of the actual system.

The solution to the lighting problem is to have three-dimensional image face recognition, and thermal imaging face recognition.

But these two technologies are far from mature, and the recognition effect is not satisfactory.

A rapidly developing solution is the active near-infrared image-based multi-light face recognition technology.

It overcomes the effects of changing light and has achieved superior recognition performance, with overall system performance exceeding 3D image face recognition in terms of accuracy, stability and speed.

This technology has developed rapidly in the last two to three years, allowing face recognition technology to gradually move towards practicality.

The human face and other biological features of the human body (fingerprints, iris, etc.) as inherent, its uniqueness and good characteristics are not easy to be copied for the identification of the necessary prerequisites, and other types of biometrics compared to the face recognition has the following characteristics:

Non-compulsory: Users do not need to be specialized with the face capture device, almost unconscious state can be

Non-compulsory: the user does not need to cooperate with the face acquisition equipment, almost unconsciously, to obtain face images, so that the sampling method is not "compulsory";

Non-contact: the user does not need to contact the equipment directly to obtain face images; Concurrency: in the actual application of the scenario can be carried out in a number of faces of the sorting, judging and recognizing; in addition to this, but also in line with the visual characteristics: In addition, it is also in line with the visual characteristics of "recognizing people by their appearance", as well as the characteristics of simple operation, intuitive results, and good concealment.
