摘要 本文提出了一种具有几何变换撸棒性的动态图像水印技术 .一个沿时间轴上的模板嵌入到动态图像序列中的每个水印最小段 (WatermarkMinimumSegment)内 .利用预先嵌入的时间轴上模板 ,可以恢复受几何仿射 (affine)变换攻击后的含水印动态图像帧 ,仿真试验结果表明本文提出的动态图像水印技术 ,经仿射变换攻击后仍是鲁棒的 . A video watermarking which resists affine transformations is proposed. A template along the time axis is inserted in each Watermark Minimum Segment (WMS) of the video sequence. Experimental results show that the watermark information can be detected blindly in watermarked frames subjected to reasonable affine transformations.
