摘    要:对宿主视频序列中每一帧的亮度通道经过提升小波处理后,选择相邻图像方块的中高频小波细节子带,根据人类视觉屏蔽特性嵌入水印,并且应用水印公式构造特殊的水印嵌入后条件,判断提取的水印可信度,然后结合水印证据之间的支持度,根据证据理论对其数据进行融合获得鲁棒水印,实验结果表明该算法具有较强的鲁棒性,能有效抵抗帧裁剪、添加噪声、帧平均、帧交换、MPEG压缩和格式转换等攻击.

关 键 词:视频水印  提升小波  证据理论

Abstract:Firstly,the lifting wavelet transformation is applied in the Y-channel of the host video,then a special embedding the watermarking formula is used to construct a special condition before embedding watermark in its middle and high frequence coefficients based on HVS and motion information.The reliability and the distortion factor of the watermark confidence are fused with the evidence theory.At last experiments have proved the algorithm can effectively resist common attacks for video watermarking and achieve higher robustness.
Keywords:video watermarking  lifting wavelet  evidence theory
