In this paper, we unify the attractive properties of shift invariance and good directional selectivity of dual tree complex wavelet transform (DTCWT), analyze motion and complex texture block for embedding according to human visual system (HVS) and MPEG motion encoding theory. Simulation results show that the algorithm is robust to AWGN, MPEG coding at high compression ratio, frame drop, frame average and frame swap.
