Abstract

The invention relates to a method and device for witness verification. The method includes: acquiring a certificate face image in a certificate photo, collecting a user's natural light face image; inputting the certificate face image into a pre-trained generative adversarial network, and obtaining the A reconstructed face image corresponding to the credential face image; wherein, the generated confrontation network is used to add preset natural light attribute information to the input credential face image, and the resolution of the reconstructed face image output by it is higher than that of the The resolution of the face image of the certificate; comparing the reconstructed face image with the natural light face image, and verifying the witness according to the comparison result. The invention can effectively improve the accuracy of authentication verification.

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...
