Robust Video Watermarking Algorithm Based on Adaptive Methods
Feng Liang · Computer Engineering and Applications Journal · 2006
Robust video watermarking algorithm is very important for copyright protection of digital video contents.In this paper,based on earlier proposed fragile watermarking algorithm,by adopting adaptive methods along with error-correcting technology,a robust,simple and fast video watermarking algorithm is proposed.In the proposed algorithm,different frames in the video sequence are watermarked with different algorithms in order that the whole bits stream is altered as little as possible.Experimental results show that the proposed new watermarking algorithm is efficient and fairly resistant to second-time coding attack and noise pollution.
