A Dynamic Video Watermarking Scheme in the DWT Domain
Maher El’Arbi, Chokri Ben Amar, Henri Nicolas · 2007
In this paper, a novel dynamic video watermarking is proposed. It takes full advantage of motion information of video content to guarantee the perceptual invisibility and robustness of the watermark. A major advantage of this technique is that the watermark is no longer at a fixed position on the screen, but moves along with moving coefficients. Embedding and extraction of the watermark are based on the wavelet network paradigm. Experimental results show that the watermarked video appears visually indistinguishable from the original video, and the proposed watermarking technique is robust enough to common video attacks.
