摘要：A video watermarking algorithm based on relative relationship of DCT coefficients is proposed in this paper. By modification of coefficients on chosen positions, the robustness of watermark embedding is ensured. Meanwhile, as the relationship of coefficients remains unchanged, the quality of video is not affected. The analysis results shows that the performance of proposed algorithm is better than the typical algorithms.
