Abstract

In Free-View Television (FTV) system, the user can freely generate a realistic arbitrary view of a scene from a number of original views. The copy-right problem for free-view video content has been produced in the emerging FTV system. In this paper, we propose a spread spectrum-based multibit watermarking scheme for free-view video. The same watermark sequence is embedded into every frame of multiple views. The watermarking extraction is carried out in the DCT domain of virtual frame generated for an arbitrary view. Experimental results show that the watermark in FTV not only can be resistant to common signal processing but also can be detected from the virtual view generated for an arbitrary view.
