Abstract

The invention discloses a repeated image recognition method and device, equipment and a medium. The method comprises the following steps of: intercepting a cut image from the to-be-identified image; converting the cut image to obtain a grayscale image, a hue saturation image and a color video image; obtaining all normalized values of a local phase quantization characteristic histogram of the grayscale image through a local phase quantization method; obtaining all standard values of a first adjacent local binary pattern feature histogram of the hue saturation image through an adjacent local binary pattern method; and meanwhile, obtaining all standard values of a second adjacent local binary pattern feature histogram of the color video image through an adjacent local binary pattern method, performing sorting according to a mantissa zero padding method to obtain a matrix graph, inputting the matrix graph into a deep convolutional neural network model, and extracting texture signal frequency statistical features to obtain an identification result. According to the invention, whether the certificate or the image is copied or not can be quickly, effectively and conveniently recognized, and the recognition accuracy is improved.

Description

technical field [0001] The invention relates to the field of image classification, in particular to a method, device, computer equipment and storage medium for recapture image recognition. Background technique [0002] With the development of the credit society, more and more application scenarios (such as: application scenarios involving finance, insurance, and security) need to verify user identity through certificate recognition or face recognition. In the existing technology, the existing document verification system needs to spend a lot of time for manual verification, and with the improvement of data photography technology, there are endless ways for criminals to verify documents by re-taking images. If no re-taken images are identified, the There will be security issues for user information. Contents of the invention [0003] The present invention provides a method, device, computer equipment and storage medium for remake image recognition, which realizes fast, eff...
