摘要
研究一种针对H.264编码的帧间预测块划分视频水印算法,该算法先对水印图像进行二值处理并经Arnold置乱,然后在H.264帧间预测编码时,根据水印二值序列选择不同的区块划分将水印值嵌入进去。实验结果表明,该算法具有较好的实时性、鲁棒性。
Studing on one kind of H.264 encoded video watermarking inter-frame prediction block division algorithm,the algorithm carries on two values of the watermark image processing and scrambling through the Arnold,then selects a different block division in H.264 inter-frame prediction encoding according to the two values sequence of the watermark,and embeds the watermark value into it.Experimental results show that the algorithm has good timeliness,robustness.
