A double video watermarking algorithm based on AVS
Sun Miao · Journal of Hebei University of Technology · 2013
A real-time double watermark information hiding algorithm based on AVS video codec standards is proposed.On the one hand,after the chaotic scrambling,the picture watermark is imbedded into I-VOP 8*8 block's fifth nonzero residual coefficient;On the other hand,the text watermarking is embedded into motion vector of P-VOP by reducing the scope of 1/4 pixel motion search elements with the AVS standards.Image watermark combined with text watermark has presented the diversity of the hidden information.Experimental results show that such algorithm has lower complexity with less change and less video distortion.It can meet the needs of real-time processing of video.
