摘要
通过分析已有的基于DCT变换的视频水印算法,提出了一种充分考虑人眼视觉特性、并通过采用水印嵌入控制策略对特定位置DCT系数进行修改以嵌入水印的方案。新算法易于实现,具有较高的鲁棒性。
This paper introduces the characteristics of the DCT-based digital video watermarking techniques that have been developed, and then proposes a digital watermarking algorithm by modulation of corresponding DCT coefficients according to human visual system,in which an embedding strategy is applied. The proposed method is easy to be implemented and has enough robustness.
