Embodiment 1

[0033] figure 1 A flow chart showing a watermark integrity checking method according to an embodiment of the present invention, such as figure 1 As shown, the method may include the following steps:

[0034] S101: Obtain an image to be inspected. Here, the image to be inspected may be any one of image types such as a single-channel image, a multi-channel image, or a video frame image in a video.

[0035] S102: Crop the image to be inspected based on the location information of a predetermined region of interest of the image to be inspected to obtain an image block to be inspected. Here, the specific type of location information is set according to the type of predetermined ROI. For example, when the predetermined ROI is a polygonal region, the location information can be the vertex coordinates of the predetermined ROI; when the predetermined ROI is a circle When creating a shape area, the location information can be the center coordinates and radius of the predetermined ar...

Abstract

The invention discloses a watermark integrity inspection method, electronic equipment and a readable storage medium. The method includes: acquiring an image to be inspected; cutting the image to be inspected based on the position information of a predetermined region of interest of the image to be inspected, and obtaining the image to be inspected. Inspect the image block; perform watermark identification on the image block to be inspected to obtain the watermark feature information to be inspected; compare the watermark feature information to be inspected with the predetermined watermark feature information corresponding to the watermark feature information to be inspected to obtain the watermark integrity of the image to be inspected test result. By implementing the present invention, the automatic inspection of the integrity of the watermark can be realized, the reliability of the inspection result is improved, and the image block to be inspected is obtained by cutting the image to be inspected according to the position information of the predetermined interest area of ​​the image to be inspected. The verification can greatly reduce the amount of data that needs to be verified finally, and improve the verification efficiency of the integrity verification method of the watermark.

Description

technical field [0001] The invention relates to the technical field of multimedia information security, in particular to a watermark integrity checking method, electronic equipment and a readable storage medium. Background technique [0002] The dissemination of digital audio and video content has become increasingly popular with the popularization of digital broadcasting and broadband networks.
