AI Technical Summary

Technical Problem

Existing deep learning-based video watermarking technologies suffer from watermark embedding strength due to the interdependence of channel probability values ​​caused by the Softmax function, which leads to the loss of some watermark information and reduces the robustness of the watermark.

Method used

A video watermark embedding method based on channel spatial attention mechanism is adopted. By extracting spatial and channel feature information of video sequences, a weight transformation module is used to generate a weight matrix, eliminating the influence of the Softmax function on the independence of feature information, and optimizing the watermark embedding position and strength.

Benefits of technology

It improves the performance of watermark embedding, enhances the robustness and readability of watermarks, improves the training and optimization performance of models, and enhances the ability to resist attacks.
