How many types of face recognition are there?

The types of face recognition can be classified according to the recognition technology and algorithm technology adopted:

Technically, it can be divided into 2D visible light plane algorithm face recognition and 3D structured light face recognition. The difference between them is that 2D visible light recognition can complete face registration with photos; Three-dimensional structured light face recognition needs to collect and model three-dimensional face data in front of the corresponding recognition equipment to complete registration.

According to whether the living body can be distinguished, it can be divided into ordinary face recognition and living face recognition. The difference between the two is that ordinary face recognition does not have living judgment, and photos and videos may be used for recognition; In the living face recognition, it can effectively avoid all kinds of deceptive recognition by detecting and judging the recognition object through the face recognition algorithm.
