A Color Video Watermarking Algorithm Based on DTCWT and Motion Estimation

In this paper, we unify the characteristic that motion region is retained in MPEG encoding and human visual system (HVS), propose a color video watermarking algorithm based on dual tree complex wavelet transform (DTCWT) and motion estimation. The watermark is embedded in motion block with highly texture, which analyzed by DTCWT with its attractive properties of shift invariance and good directional selectivity. The simulation results show that the algorithm is robust to AWGN, MPEG coding at high compression ratio, frame drop, frame average and frame swap.
