A novel blind video watermarking scheme is proposed.In this scheme
independent component analysis (ICA) is used to extract the motion component between the consecutive frames and the watermark is embedded into the wavelet coefficients of the motion component according to the mean of the neighboring wavelet coefficients.Motion component is important to the video
but it is not obviously affected by compression.So
the robustness is improved by embedding the watermark into the motion components.Frame-based motion extraction avoids the repeat operations of block-based extraction and reduces the complexity.Embedding watermark in wavelet domain disperses the effects caused by watermark to the whole frame.Better invisibility can be achieved.The simulation results show that the proposed scheme can preserve high video quality.The watermark can be extracted blindly and is robust to common video processing with little probability of false positive.
