Abstract

The invention discloses a face recognition method and a face recognition device based on fusion of multiple frames of face features in a video. The face recognition method comprises the following steps: acquiring n frames of face images to be recognized in a monitoring video, wherein n is greater than or equal to 1; selecting m frames of face images from the n frames of face images, and performingfeature extraction on the m frames of face images to generate feature vectors {fi} in one-to-one correspondence with the m frames of face images, wherein i is 1, 2, ...., m, and m is greater than orequal to 1 and smaller than or equal to n; fusing the m feature vectors {fi} into a feature vector r, and comparing the feature vector r with face features in a database so as to recognize a face identity in the monitoring video. By the face recognition method provided by the invention, multiple frames of face images in the monitoring video are detected, feature extraction is performed thereon, and the extracted multiple face features are fused into one face feature for recognition, so that not only is the number of feature comparisons reduced, but also influence of face angle deflection, motion blur, backlight and the like on face image feature extraction is reduced; the face recognition method and the face recognition device are applied to a multi-dynamic video acquisition environment and can effectively improve the face recognition accuracy.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence image processing, in particular to a face recognition method and device based on fusion of face features of multiple frames of video in a multi-dynamic environment. Background technique [0002] With the popularity of video surveillance systems and increasing development needs, face recognition has made great progress. Nowadays, the tentacles of "mobile electronic eyes" are slowly penetrating into every corner of the city, playing an increasingly important role in protecting our "safe city". A safe city is also an important measure of a city's modern management level, and an important measure to realize the security and stability of a city and even the entire country. Only by establishing a reasonable and effective urban video surveillance management system can the government management department discover problems at the first time and propose countermeasures and emerge...
