Method and device for face recognition

Abstract

The invention provides a method and a device for face recognition. The method includes an M frame image acquired through an image acquisition device is obtained; when information of N faces of N people is contained in the M frame image, information of each face in the N faces is subjected to face recognition to obtain N first recognition records; when information of N faces at second time of the N people is contained in a number i+j frame image of the M frame, information of each face in the N faces is subjected to face recognition to obtain N second recognition records; and recognition results of the N faces of the N people are determined at least based on the N first recognition records and the N second recognition records. According to the method, the technical problem that a plurality of faces are inaccurately recognized or detection omissions occur in recognition processes in the prior art for face recognition cannot be accurately performed in prior face recognition in the condition of face increases or decreases in videos is solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a face recognition method and device. Background technique [0002] Face recognition is a kind of biometric identification technology. A face recognition system first collects face images and detects face regions, and then compares the detected face images with pre-stored face images to identify the identity of each face. From the perspective of application, face recognition includes two categories: [0003] Identification: Recognize the identity of the person based on the face image, that is, to solve the problem of who is it, for example, in the public security system, the identity of the person is found from the database based on the photo of the person. [0004] Identity confirmation / verification: Judging whether the face in the image is the designated person, that is, solving the problem of whether it is a certain person, such as the identity verification of th...

Problems solved by technology

[0008] The present invention provides a method and device for face recognition, which is used to solve the problem that the existing face recognition cannot accurately perform face recognition in the case of increasing or decreasing faces in the video in the prior art. As a result, the recognition is inaccurate during multi-face recognition, or there is a missed detection during the recognition process, which makes the technical problem of low accuracy of face recognition. The specific technical solutions are as follows:
