Abstract

The embodiment of the invention provides a face recognition method and device, and relates to the technical field of artificial intelligence, and the method comprises the steps: calculating a featurevector corresponding to a second image; Calculating cosine similarity between the feature vector of the second image after normalization processing and the feature vector of each preset face image inthe plurality of preset face images after normalization processing; If all the calculated similarities are smaller than a preset similarity threshold value, outputting first prompt information, and using the first prompt information for prompting that the target user fails to verify; If at least one of the calculated similarities is greater than or equal to a preset similarity threshold, screeningout a preset face image corresponding to the maximum similarity; And taking the user associated with the preset face image corresponding to the maximum similarity as a candidate user. Therefore, according to the technical scheme provided by the embodiment of the invention, the problem of low face recognition speed caused by low similarity calculation efficiency in the prior art can be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of artificial intelligence, in particular to a face recognition method and device. 【Background technique】 [0002] Face recognition is a biometric technology for identification based on human facial feature information. Use a video camera or camera to collect images or video streams containing human faces, and automatically detect and track human faces in the images, and then perform facial recognition on the detected faces. [0003] In the process of face recognition, it is necessary to calculate the similarity between the images collected on-site and the pre-stored images in the database. In the case of a large number of images, the low efficiency of similarity calculation leads to slow face recognition. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides a face recognition method and device to solve the problem in the prior art that the speed of face recog...
