基于颜色空间转换的自适应视频多重水印算法

针对现有多重水印算法的一些不足,提出了一种自适应稳健性视频多重水印算法。该算法结合置乱技术、颜色空间转换及人类视觉系统特性(HAS),将代表不同版权意义的多重二值图像水印自适应地嵌入到视频帧亮度分量的DCT中低频系数中,实现了多重水印在视频载体中的嵌入及提取,并且多重水印提取时不需要原始视频的参与。实验结果表明,该算法能够有效地平衡透明性与稳健性之间的关系,在保证视频质量的同时对常规视频攻击具有较好的稳健性。

Adaptive Video Multi-watermarking Algorithm Based on Color Space Conversion

A robust adaptive multiple video watermarking algorithm is proposed for some of the current lack of multi-watermarking algorithm.The algorithm combines the scrambling technology,color space conversion and visual system characteristics adaptively embedded the multiple binary image watermarking in the DCT middle-low-frequency coefficients of the original video frame's brightness component.The algorithm can achieve the multi-watermarking embedded in the video carrier and the blind extraction.The experimental r...
