Abstract

The present invention relates to a people and certificate verification method and device. The method comprises a step of obtaining a certificate face image in a certificate picture and collecting a natural light face image of a user, a step of inputting the certificate face image into a pre-trained generative adversarial network, and obtaining a reconstruction face image corresponding to the certificate face image according to the output of the generative adversarial network, wherein the generative adversarial network is used for adding preset natural light attribute information to the inputted certificate face image, the resolution of the outputted reconstruction face image is higher than that of the certificate face image, and a step of comparing the reconstruction face image and the natural light face image and carrying out people and certificate verification according to a comparison result. According to the method and the device, the accuracy of people and certificate verification can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to methods, devices and others for witness verification. Background technique [0002] With the rapid development of face recognition technology, the witness verification system has also received widespread attention, and the demand for practical application scenarios such as security and banking has increased dramatically. In the heterogeneous face recognition technology, the difference in modalities makes the face images very different, which is the main reason for the difficulty in accurate identification. The problem of witness verification belongs to heterogeneous face recognition, which refers to judging whether the lower-resolution ID photo face image matches the higher-resolution natural light face image. [0003] The biggest problem of the witness verification system is that the accuracy of the verification is low, and based on the traditional heterogeneous face r...
