Abstract

A method and device for face recognition, an electronic device and a storage medium are provided in an embodiment of the present invention. The method and apparatus are particularly adapted to receiveimage data including a face image to be recognized, face detection is carried out on the image data, so that that face image is obtained, and then pose alignment processing and pixel value alignmentprocessing are carried out on the face image in turn, then, the pre-trained face feature extraction model is used to extract the features of the face image after the pixel value alignment processing,and the face features of the face image are obtained. Finally, the cosine distance between the face features and the features of the face image to be compared is calculated, and the face recognition result is obtained according to the cosine distance. The scheme enhances the contrast of face image, simplifies the data distribution of face image, and makes the model of face feature extraction converge better, especially for the face image with uneven illumination, which solves the problem of face recognition in difficult scenes.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a face recognition method, device, electronic equipment and storage medium. Background technique [0002] With the development of deep learning technology, the accuracy of face recognition has been improved more and more, and face recognition technology has been applied in many scenarios. Generally speaking, the face recognition process is divided into three steps, face detection, face alignment, face feature extraction and comparison, face detection is mainly to detect the position of the face from a large picture, face alignment It is mainly to calibrate the posture of the face, and the face feature extraction and comparison is to structure the face, so that the face feature distance of the same person is as small as possible, and the face feature distance of different people is as large as possible. [0003] In some extreme scenarios, the accuracy of fac...
