A watermark identification method for video copyright

Aiming at identifying extracted watermark for video copyright, this paper proposes a novel method based on synergetic pattern recognition. A meaningful binary image is serially processed into watermarking signal and then embedded into the AC coefficients in DCT domain of video frames. The algorithm of synergetic pattern recognition is discussed in detail and used in the extracted video watermark identification. With lots of experiments, the results show that the proposed method is effective, fast and robust.
