Abstract

The invention discloses a screen shooting picture detection method and device, electronic equipment and a storage medium. The method comprises the following steps: firstly, obtaining a target picturecorresponding to a target area from a to-be-detected picture; then, on one hand, edge features are extracted from the target picture; and on the other hand, predicting the probability that the targetpicture contains the moire features by using a pre-trained probability prediction model, and finally, comprehensively analyzing whether the target picture is a screen shot picture or not in combination with the probability that the target picture contains the moire features in the edge feature extraction result. The method has the advantages of being stable in feature, high in classification precision and high in robustness in application of a picture auditing scene, especially a real estate certificate picture auditing scene, and the auditing cost can be effectively saved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, electronic equipment and storage medium for detecting screen-captured pictures. Background technique [0002] With the development of network and information technology, in the application field involving data review, users upload the materials to be reviewed to the network, and then conduct online review of the materials to be reviewed through intelligent detection technology, thereby replacing manual review. [0003] In most application scenarios, based on the requirements of the reviewer, the picture to be reviewed uploaded by the user should be a picture obtained by using a camera to take pictures of real objects. Therefore, before identifying the content of the picture to be reviewed, it becomes a necessary review link to detect whether the picture to be reviewed is a screen shot obtained by the user using a camera to shoot a lighted electro...
