Abstract

The invention provides a face comparison method and device, and the method comprises the steps: obtaining a to-be-recognized face image; inputting the face image to be recognized into the face comparison model to obtain a face comparison result output by the face comparison model; wherein the face comparison model is obtained by training based on a sample image and a texture label corresponding to the sample image; the face comparison model is used for performing color adjustment and texture filling on face image features extracted based on the to-be-recognized face image and then performing face comparison with pre-stored face comparison features. According to the invention, color adjustment is carried out on the face image features by using the color features extracted by the face comparison model so as to eliminate color differences caused by image source differences, and texture filling is carried out on the face image features by using the texture features extracted by the face comparison model. Therefore, the loss of texture features of face image features caused by a color-removed region is avoided, and the accuracy of subsequent face comparison is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a method and device for comparing human faces. Background technique [0002] With the rapid development of Internet technology, it is particularly important to ensure the security of user accounts through face verification. Face verification is a branch in the field of face recognition. Face verification is to verify the face to be recognized and the pre-stored face image to determine whether it is the same person, that is, the problem of "same or not". One-to-one matching process. The face verification algorithm first finds the stored face image according to the identity (such as name or user name) claimed by the person to be identified, and then compares the stored image with the face image to be identified according to a certain decision or matching principle. Comparisons are made to determine the authenticity of the identity of the person to be identif...
