Novel Scheme for Watermarking Stereo Video
Zengnian Zhang, Zhongjie Zhu, Lifeng Xi · 2007
Based on previous research work on both digital watermarking and stereo video, a novel scheme for watermarking stereo video is introduced. Firstly, an adaptive watermarking model based on disparity vectors is proposed after analyzing the characteristics of stereo video. Then a new watermarking algorithm is introduced. Adaptive scheme and pre-encoding with low density parity check (LDPC) codes are employed to enhance the watermarking robustness. Watermark can be blindly extracted without the need of original video sequence. Experimental results reveal that the proposed algorithm is effective, which can resist some common attacks such as recoding and noise pollution.
