摘要

根据H.264视频编码标准，提出了一种基于运动矢量和模式选择的脆弱视频水印算法。通过选择分裂较小的运动矢量，并将运动搜索中的Laragian函数最小化，将脆弱水印嵌入到具有最佳速率失真能力的运动矢量中。实验结果表明，该算法对重编码处理具有较好的灵敏度，对视频质量和码率的影响较小。

Motion vector and mode selection based fragile video watermarking algorithm

According to H.264 video encoding standard, a fragile video watermark algorithm based on motion vector and mode selection is proposed. By selecting the motion vector with small splitting and minimizing the Laragian function in motion search to embed the fragile watermark into the motion vector that have the best rate distortion capability. Experimental results show that the proposed algorithm can achieve better sensitivity to the re-encoding processing and bring little influence to video quality and bit rate.
