Abstract:The paper presents a novel and robust video watermarking scheme based on fractal theory in DCT domain of every I-frame of video stream. Firstly, we select I-frames from video stream as objects to embed watermarks. Before watermarking embedding, we divide every I-frame into range block pool and domain block pool in DCT domain. Secondly, we search for embedding blocks from range block pool according to the fractal theoretic. Finally watermarks are embedded into the embedding blocks and detected according to JND model. Some tests prove this method to be robust, simple and easy to use.
