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。

Abstract: 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.
