Real-time face recognition method and system and electronic equipment

Abstract

The invention discloses a real-time face recognition method, a real-time face recognition system and electronic equipment. The real-time face recognition method comprises the following steps: judgingwhether the central position of a face image region is located in a preset effective face region or not, and judging whether the face image region can be expanded or not to obtain an expanded face image region; and the expanded face image area is inputted to a face living body recognition network model to output the probability that the face in the image is a false face, and whether the probability of the false face is greater than a preset probability threshold is judged so as to perform face calibration operation on the face image area to obtain the calibrated face image area. And performingface recognition operation on the calibrated face image area through a face recognition network model, so as to select a face closest to the face in the image from a face database as display output.According to the invention, true and false faces can be distinguished in real time, and the recognition precision is high.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a real-time face recognition method, system and electronic equipment. Background technique [0002] Face recognition technology is an identification technology based on facial features. Image-based face recognition technology has been widely used in various fields because of its non-contact, non-forced and natural nature. However, in the field of practical application, especially in the field of security, the reliability and security of the face recognition system are extremely high. Not only must the identity of the face be identified, but also various face attack methods must be effectively prevented. [0003] In the prior art, there are very few live recognition technologies for fake face attacks. Most of the live recognition technologies adopt the method of inputting the face area, and judge the true and false faces by learning the texture, illumination and other ch...

Problems solved by technology

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a real-time face recognition method, system and electronic equipment, which is used to solve the problem in the prior art that it is difficult to distinguish true from false only through the face area. It is impossible to distinguish real and fake faces in real time, and the recognition accuracy is low, so it cannot resist common fake face attacks
