This paper presents a watermarking scheme that embeds a signature in video objects for the MPEG-4 video standard. The different constraints associated with this standard are quite different from classical video watermarking schemes. The mark detection had to be achieved after different video object manipulations such as rotation or scaling operations. Principal component analysis and warping methods are used to enable the synchronization of the mark after geometric manipulations. The embedding of the mark is done adding an oriented random sequence and the detection of the mark is processed using a correlation criterion. The different results point out the fact that the presented scheme can detect the mark after bit-rate modification, object shape sub-sampling and geometric manipulations (scaling and rotations).
