摘　　要：提出了一种基于能量差比率的DEW视频水印算法,该算法选择在I帧视频图像块能量(纹理)分布均匀的区域嵌入水印,每个I帧中嵌入的水印相同。实验结果证明,该算法水印鲁棒性好,码率稳定,检测可靠性高。A DEW video watermarking algorithm based on energy difference ratio was proposed. This algorithm embeds watermarks in energy-equally-distributed areas of I-frame video image blocks. Every I-frame has the same embedded-watermarking. Experimental results show that the proposed watermarking algorithm not only has better performance in the aspect of robustness but also has stable rates and high reliability in the test.
