The present application provides a video processing method, device, computer equipment and storage medium, belonging to the technical field of image processing. The method includes: obtaining watermark information in response to a watermark adding instruction for the first video, performing binary conversion on at least one character in the watermark information to obtain binary data corresponding to the character; The pixel value of the image is adjusted, wherein the frequency change trend corresponding to the adjusted pixel value of the first image corresponds to the binary data; based on the adjusted first image, a second video after adding watermark information is generated. This application uses the frequency change trend corresponding to the pixel value to represent the watermark information. After the video is attacked, the frequency change trend is not easy to be destroyed, and the watermark information can still be represented, and it can still be extracted from the attacked video. Accurate watermark information, watermark information can effectively resist attacks and enhance robustness.
Description
Technical field [0001] The present application relates to the field of image processing, and more particularly to a video processing method, device, computer device, and storage medium. Background technique [0002] Digital watermarking technology is an effective way to copy rights protection, which can be used to copyright protection for video, such as protecting some games via watermarking technology. By digital watermarking technology, the copyright information of the video can be used as a digital watermark, embedded in the video. Digital watermarks embedded in video can identify the copyright belongings of the video, and digital watermark is hidden in the video, which is not easy to be detected and perceived. The copyright protection of the video can be processed from the video to extract digital watermarks from the video by embedding digital watermarks in the video. [0003] Video embedded in digital watermarks can be zoomed, rotated, translated, distorted, compressed durin...
