[0021] In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, the present invention provides a flow chart of a face recognition method for updating cosine angle loss function parameters in real time, and the face recognition method includes the following steps:
[0023] (1) Collect face images, classify face images by individuals, and label each face image according to the classification results;
[0024] (2) After performing horizontal flipping, denoising, brightness enhancement and contrast enhancement processing on the face image collected in step (1), the face image data set is obtained, and the face image data set is divided into batches;
[0025] (3) Initialize the cosine value of the cosine angle loss function to enlarge the scale s and the cosine angle interval m, so that , , the cosine angle loss ...
