A Robust Video Watermarking Method for Random Detection
Juan Hu · Journal of Engineering Graphics · 2008
Random detection is one of the key issues of video watermarking.The current video watermarking lacks effective techniques for random detection.A method of robust video watermarking is provided to apply to random detection.Firstly,the watermarking data are coded and replaced according to BCH.And then,the coded data and synchronization codes are embedded into the candidate middle frequency coefficients in DCT domain.The experiment shows that the random detection algorithm has performed well in anti-noise,video compression and cutting,and can achieve the watermark random detection and watermark byte alignment.
