摘要 根据视觉的色度敏感性,提出了一种能够抵抗格式转换等多种攻击的鲁棒视频流水印技术。针对失真积累效应,采取了相应的补偿措施来降低失真度,而且在水印嵌入过程中可以利用视频解码器,运算量小,效率高。 This paper presents a video watermarking technique that is r obust against format transformation based on chroma sensitivity.The algorithm adopts a compensative technique to overcome the influence of accumulating disto rtion of video,and the watermark embedding is able to make use of video decoder with little computation load and high efficiency.
