Watermark embedding method and related device

Abstract

The invention discloses a watermark embedding method and a related device, a video to be processed is subjected to frame extraction to obtain an initial video frame set, the initial video frame set comprises a plurality of continuous video frames, and two video frames in the initial video frame set can serve as a first video frame and a second video frame corresponding to the first video frame. The method comprises the steps of determining an initial residual error between a first video frame and a corresponding second video frame, determining a target residual error rule corresponding to an initial video frame set according to a to-be-inserted bit corresponding to the initial video frame set and a corresponding relation between the bit and a preset residual error rule, and adjusting the initial residual error according to the target residual error rule to obtain a reconstruction residual error, according to the method, the first video frame and the corresponding reconstruction residual error are reconstructed to obtain the third video frame, the reconstruction video corresponding to the to-be-processed video is determined according to the third video frame, watermark embedding is realized by adjusting the residual error of the two video frames, the watermark information is not interfered by the video processing process, and the robustness of the watermark is improved.
