Robust Adaptive Video Watermarking Algorithm Based on HVS
Cheng Yan · 2008
A robust adaptive Video Watermarking algorithm based on Human Visual System(HVS)was proposed.By comparing the direct current DCT coefficients of the I frame and its neighbor frame of the video,a fast moving image block set was chosen.The new algorithm embedded watermarking bits adaptively in proper place for some image block,which was decided based on HVS.Experiments show that the proposed algorithm is robust against MPEG compression,also the attacks of RST.
