Problems solved by technology
Although the digital watermark still exists in the attacked video, the digital watermark has been misplaced, and the digital watermark extracted from the attacked video will have errors and is not accurate enough
Digital watermarking cannot effectively resist attacks, and its robustness is weak

The invention provides a video processing method and device, computer equipment and a storage medium, and belongs to the technical field of image processing. The method comprises the steps of obtaining watermark information in response to a watermark adding instruction for a first video, and performing binary conversion on at least one character in the watermark information to obtain binary data corresponding to the character; adjusting a pixel value of a first image in the first video based on the binary data, the frequency change trend corresponding to the adjusted pixel value of the first image corresponding to the binary data; and generating a second video added with the watermark information based on the adjusted first image. According to the invention, the watermark information is expressed by the frequency change trend corresponding to the pixel value, after the video is attacked, the frequency change trend is not easy to damage, the watermark information can still be expressed,the accurate watermark information can still be extracted from the attacked video, the watermark information can effectively resist the attack, and the robustness is enhanced.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a video processing method, device, computer equipment and storage medium. Background technique [0002] Digital watermarking technology is an effective method of copyright protection, which can be used to protect video copyright, such as protecting some game videos through watermarking technology. Through the digital watermarking technology, the copyright information of the video can be embedded into the video as a digital watermark. The digital watermark embedded in the video can identify the copyright owner of the video, and the digital watermark is hidden in the video, which is not easy to be detected and detected. Through a method corresponding to embedding a digital watermark in a video, the digital watermark can be extracted from the video to prove the copyright owner of the video, thereby realizing copyright protection. [0003] Videos embedded wit...
