Adaptive Video Watermarking Algorithm Based on Matrix Scrambling
Yanshen Liu · 2005
Digital watermarking technology of video image is a hot topic in present watermarking researching area.In this paper,a adaptive video watermarking scheme based on MPEG-2 motion vectors is proposed,using matrix scrambling computing target group of pictures for watermark clip,combided human visual system,chosing target component motion for watermarks bit.Experimental show that it is robust to special video watermarks attack,and has faintness influence on the visual effect of pictures.
