Embodiment Construction

[0022] Due to the increase or decrease of faces in the video in the prior art, face recognition cannot be accurately performed in the existing face recognition, resulting in inaccurate recognition during multi-face recognition, or inaccurate recognition during the recognition process. The technical problem of missed detection, that is to say, in the existing technology, when carrying out face recognition in the video, generally all can appear a plurality of people's faces in this video, at this moment the recognition system in the face recognition device will be in the video The general recognition process is to collect the features of all faces in a frame of image, and then compare the face features with the face features in the pre-stored database, and finally get the corresponding face features. identity information, but under different circumstances, the facial expression of the human face will change, so the facial features will also change to a certain extent, so that rec...

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...
