A Novel Differential Energy Video Watermarking Based on Watson Visual Model

This paper proposes a novel differential energy watermarking based on the Watson visual model, which inserts robust watermark into video streaming according to the differential energy theory. This algorithm can control the watermark´s embedding intensity of sub-low AC coefficients in the video streaming adaptively based on the Watson visual model. And it also can choose the region to embed watermark according to the relationship between the energy adjustable threshold and their differential energy. So watermark not only meets the non-visual perception, but also has the better robustness. Experiments show that this algorithm has strong robustness and security against the usual video attacks such as noise, filter and frame attack etc with low complexity of energy computation. This algorithm will be applied to the multimedia copyrights protection.
