Dual Embedding Domain Based Video Robust Reversible Watermarking Algorithm
Aiming at the compatibility problem of robustness and reversibility of existing video watermarking algorithms,a video robust reversible watermarking algorithm based on dual-domain marking was proposed.This algorithm used traditional robust watermark splicing technology to embed watermark information in the quantized DCT coefficient domain of H.264 video coding;it used two-dimensional histogram migration technology in the motion vector domain to embed auxiliary information to achieve watermark extraction at the decoder and lossless recovery of the original video.Experimental results show that the algorithm in this paper has good invisibility.The peak signal-to-noise ratio and average structural similarity of the experimental video are 44.7537 dB and 0.9902 respectively.The bit rate expansion is all at 16.74％and below.At the same time,it is resistant to distortion attacks of different strengths.It has strong robustness.The normalized cross-correlation coefficients of experimental videos are all above 0.970,and the bit error rates are below 0.068.
