Chaotic encryption and error propagation control based video watermarking for AVS in compressed domain
Han Jia · Jisuanji yingyong yanjiu · 2009
According to the security of watermarking and the problem of error propagation,proposed a novel for AVS. Two compensation methods to overcome the error propagation after watermark embedding into motion vectors,which would greatly decrease the error propagation. Moreover,the chaotic encryption of watermark greatly improved the security of watermarking. Experimental results on several test sequences demonstrate that the proposed approach controls the error propagation well and can meet the requirements of blind detection and imperceptibility.
