Özet:

 

Because of the large amount of frames, similarity between  frames and temporal attacks (frame dropping, frame averaging, frame  swapping etc.), the process for video watermarking is more difficult  than that for image watermarking.  Current image watermarking methods  are limited to solve all these difficulties.  We propose a novel video  watermarking system based on the Hidden Markov Model (HMM).  This  novel watermarking scheme splits the video sequences into a Group of  Pictures (GOP) with HMM. Portions of the binary watermark are embedded  into each GOP with a wavelet domain watermarking algorithm.  The  embedding process is the standard additive algorithm [1] in low  pass (LL) and high pass (HH) bands in the wavelet domain.  This novel  system increases the robustness against geometric and temporal  attacks, and increases the quality of the watermarked video.
