H.264-based watermarking for compressed video
Jianrong Wang · Journal of Computer Applications · 2009
Concerning the new features of the H.264/AVC video coding standard,a schema based on H.264 low bit-rate video stream was proposed.This paper improved the robustness and effectiveness of the traditional Differential Energy Watermarking(DEW) using the formula of energy distribution.The watermark extracting was carried out in the decode time and the original video was not needed during the process.The experimental results show that this schema can maintain a small change in bit-rate and keep small distortion,which means the proposed schema is effective.
