论文摘要

Digital video watermarking was introduced at the end of the last century to provide means of enforcing video copyright protection. Video watermarking involves embedding secret information in the video. In this paper, we proposed a digital video watermarking technique based on identical frame extraction in 5-Level Discrete Wavelet Transform (DWT). In the proposed method, first the host video is divided into video frames. Then from each video frames one video frame called identical frame is selected for watermark embedding. Each identical frame is decomposed into 5-level DWT, and then select the higher Subband coefficients to embed the watermark and the watermark are adaptively embedded to these coefficients and thus guarantee the perceptual invisibility of the watermark. For watermark detection, the correlation between the watermark signal and the watermarked video is compared with a threshold value obtained from embedded watermark signal. The experimental results demonstrate that the watermarking method has strong robustness against some common attacks such as Gaussian noise adding, Salt & pepper noise adding, frame dropping.
