Embodiment Construction

[0102] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0103] The remake image recognition method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The server 104 obtains the image to be recognized by the terminal 102, performs Fourier transform on the obtained image to be recognized, and obtains a Fourier spectrum feature map; the server 104 extracts LBP (Local Binary Pattern, local binary pattern) features from the Fourier spectrum feature map value, calculate the statistical probability of th...

Abstract

The invention relates to the technical field of image detection, in particular to a reshot image recognition method and device, a computer device and a storage medium. The method comprises the steps of obtaining a to-be-identified image; carrying out Fourier transform on the obtained image to be identified to obtain a Fourier spectrum feature map; extracting an LBP feature value from the Fourier spectrum feature map; generating LBP histogram statistical data for representing the LBP eigenvalue statistical probability according to the extracted LBP eigenvalue; inputting the LBP histogram statistical data into a neural network model, and performing identification processing on the LBP histogram statistical data through the neural network model to obtain a first reshooting probability; and when the first reshooting probability reaches a probability threshold, determining that the to-be-identified image is a reshot image. By adopting the method, the security problem of user information caused by image copying can be avoided.

Description

technical field [0001] The present application relates to the technical field of image detection, in particular to a remake image recognition method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of computer technology and Internet technology, opening an account online or handling important business online may require users to take and upload corresponding images through mobile terminals or web cameras and other equipment, such as the user's ID image or the user's real image . [0003] However, the uploaded image may not be the real image obtained by the user by taking pictures of himself, or the certificate image obtained by taking a real certificate, but by reproducing the picture displayed on the display screen of a computer or mobile phone, so there is forgery The problem of user images, if these remake images are not identified, will lead to security issues of user information.
