| Abstract(in English) | Watermarking techniques proposed up to now have some measure of robustness against non-geometrical alteration, however, most of them are not so robust against geometrical alteration. As also for video watermarking, small translation, scaling, rotation, affine transformation can be effective attacks on the watermark. In this paper, we propose an image correction scheme for video watermarking extraction. This scheme embeds 'patchwork' into digital video data for detection of positions, and corrects the images attacked by geometrical alteration on the basis of the detected positions. We also show the simulation result of applying proposed scheme to the conventional watermarking techniques. |
