Embodiment Construction
[0099] 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.
[0100] 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, and generates a Haar feature map according to the image to be recognized; the server 104 extracts the LBP (Local Binary Pattern, local binary pattern) feature value from the Haar feature map, and calculates the LBP feature value in each feature value Statistical probability within...

The invention relates to the technical field of image detection, and especially relates 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; Generating a corresponding Harl feature map according to the to-be-identified image; Extracting an LBP feature value from the Harl feature map; Calculating the statistical probability of the LBP characteristic value in each preset characteristic value range; Inputting the statistical probability of the LBP characteristic value into a neural network model, and carrying out recognition processing on the statistical probability of the LBP characteristic value 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 obtained by retaking the pictures displayed on the display screens of devices such as computers or mobile phones, which will lead to There is a security issue with user information. Contents of the invention [0004] Based on this, it is necessary to addres...
