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,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,并将水印值嵌入进去.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 prediction block division algorithm,this algorithm carries on two values of the watermark image processing,then select a different block division in H.264 inter prediction encoding according to the two values sequence of the watermark,and embedding the watermark value into it.Experimental results show that the algorithm has good timeliness,robustness.
