This article proposes a reversible high-capacity watermarking algorithm for the H.264/AVC video standard. The technique applies the concept of Differential Expansion (DE) on the pixel values of the IPCM macroblocks generated by the H.264/AVC encoder. To ensure a high watermark payload, the algorithm performs the embedding in multiple layers. Initial experimental results showed that the technique not...
This paper proposes a reversible watermarking technique that utilizes the IPCM macroblocks generated by the H.264/AVC encoder. The technique applies the concept of Differential Expansion (DE) to the pixels of the luminance and the chrominance components within the IPCM macroblocks of the P-frames. The performance of the proposed algorithm was tested for a number of video sequences and compared to...
