基于H.264编码的视频水印算法

Coding Based on H.264 Video Watermarhing Algorithm

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,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,在B片少量出现的情况下可以达到最佳的效果。

One kind of H. 264 encoded video watermarking inter prediction block division algorithm is studied, this algorithm carries on two values of the watermark image processing and scrambling through the Arnold, then se- lect a different block division in H. 264 inter prediction encoding according to the two values sequence of the water- mark, and embedding the watermark value into it. Experimental results show that the algorithm has good timeliness, robustness, may achieve the best effect in the situation of appearing small amounts of B pieces.
