Shen Xu · Modern Computer · 2008
Introduces a new method to embed watermark in moving speed map of macroblock by means of cross,which bases on the formers' embedding watermark information into moving vector theory and combines MPEG coder decoder scheme and human visual system.The new method not only improves the blindness of video watermark and not affect the quality of I frame,but also increases watermarking robustness and watermark embedded is very large because of B and P frames is more than P frame in group of pictures.
