Video watermark scheme based on motion vector and mode selection
Huang Jianzhu · Computer Engineering and Applications Journal · 2011
According to the new H.264 coding standard,a video watermark scheme based on motion vector and mode selec-tion is proposed.The watermark is embedded into the motion vector with small splitting.By minimizing the Laragian function in motion search to find the motion vector that has the best rate distortion performance.Experimental results demonstrate that the algorithm can achieve robustness to the re-encoding and noise attacks with little affect to video quality and bit rate.
