Abstract

A novel drift compensation algorithm for robust H.264/AVC video watermarking scheme is proposed. The drift compensation algorithm is implemented to reduce the visual distortion, which includes the reduction of the alteration of reference blocks caused by watermarking process. In our method, motion vector residuals of macroblocks in P frame are used as payloads of watermark. Discrete Cosine Transform (DCT) is performed on the motion vector residual group to utilize the energy compact property so that robustness against lossy compression attack can be obtained. According to the experimental results, our algorithm can obtain excellent imperceptibility and can significantly diminish the distortion influence. High rate lossy compression attack can be resisted effectively and an average of 80% accuracy rate of watermark detection can be achieved. © 2012 Springer-Verlag.
