A survey of digital video watermarking

The watermark of digital images, audio, video, and other media products in general has been proposed for resolving copyright ownership and verifying the integrity of content. The definition and basic framework of watermark techniques are first introduced, and then the basic theoretical and evaluation criteria are expatiated. For further understanding, the watermark techniques from the various aspects are classified and some conventional watermark techniques and algorithms are analyzed in detail, and their scheme of video watermarking embedding and extraction are compared. At the same time, the influence of human visual system to watermark visibility is analyzed. Finally, the application field and possible research direction of digital watermark technology is pointed out.
