The invention relates to the technical field of image processing, and discloses a face recognition method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining a to-be-recognized face image and a user identification, and extracting a first image feature of the to-be-recognized face image; acquiring a registered face image based on the user identifier, and extracting a second image feature of the registered face image; normalizing the first image feature based on the normalization matrix to obtain a first normalized feature; normalizing the second image features based on the normalization matrix to obtain second normalized features; wherein the normalization matrix is obtained based on a normalization image library; wherein the proportion of the number of different types of face images in the normalized image library conforms to a preset proportion; and determining the matching degree of the to-be-recognized face image and the registered face image based on the first normalized feature and the second normalized feature. According to the face recognition method provided by the invention, the time consumed for model training canbe reduced, and the face recognition efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to a face recognition method, device, electronic equipment and readable storage medium. Background technique [0002] The application of human-computer interaction technology is becoming more and more extensive. In the field of human-computer interaction, face recognition technology is of great significance. In the face recognition method, usually the distribution of different types of face data in the training data of the face recognition model is unbalanced, and for different types of face data, the feature similarity is not uniform, resulting in a low face recognition accuracy. [0003] In order to solve the problem of uneven distribution of different types of face data in the training data of the face recognition model, in the prior art, the training data of the face recognition model needs to be re-adjusted and sampled so ...
