Abstract
In this paper, a compressed domain drift compensated reversible watermarking scheme is proposed with a high embedding capacity and the least amount of visual quality degradation for H.265/HEVC videos. Using compressed domain syntax elements, such as motion vector and transformed residual, a set of 4 × 4 Transform Blocks (TB) of similar texture are chosen from consecutive I Frames for watermark embedding. Due to texture similarity of these selected TBs, the differences between the transformed coefficients are equal or close to zero. Utilizing this difference statistics, a multilevel watermarking is inserted in the compressed video by altering near zeros values in the difference transformed coefficients. A comprehensive set of experiments have been carried out to justify the efficacy of the proposed scheme over existing literature.
