Abstract : This paper presents a watermarking scheme for image or video objects. The watermarking of video objects implies different constraints from raw watermarking methods. The mark has to be detected after object manipulations such as rotations, translations and VOL modifications. To achieve these requirements, the embedding scheme exploits the shape of the object: a random sequence is transformed to fit the scale and the orientation of the object. The detection of the mark is performed applying an inverse transform and calculating a correlation between the random sequence and the warped object. Our results illustrate the fact that the presented method is robust to object manipulation. of other VO named VOL in the Mpeg-4 context to denote Video Object Layer.
