Abstract

The present invention provides a face detection and recognition method and device. The method comprises the steps of: pre-collecting at least one side face image, wherein the at least one side face image is a face image with a set angle of deflection; extracting corresponding side face features from each side face image; obtaining images to be detected, and extracting face angle features and facefeatures to be compared from the images to be detected; determining target angles of deflection corresponding to the images to be detected according to the face angle features; determining at least one side face image to be selected corresponding to the angles of deflection and the target angles of deflection from each side face image; perform comparison of the face features to be compared and theside face features corresponding to the side face images to be selected to obtain the similarity of the images to be detected and the side face images to be selected; and according to the similarity,recognizing a target side face images as a recognition result from the side face images to be selected. The face detection and recognition method and device can achieve face recognition based on theside face image.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face detection and recognition method and device. Background technique [0002] With the development of biometric technology, more and more face detection and recognition technologies have entered people's lives. From industry users, business users, to individual users, there are urgent application needs in the fields of access control, attendance, access, bayonet, smart home, robotics, medical care, manufacturing, finance, security monitoring, etc., and have huge market prospects. [0003] At present, the face detection and recognition technology is mainly applicable to frontal faces, so the requirements for the collected images are relatively high, and the user's frontal face needs to be collected for recognition. However, in practical applications, most of the collected faces are not frontal faces, so the detection method in the prior art cannot realize face recogn...
