位域实时视频水印算法

在目前数字水印算法中，图像水印的算法远多于视频水印，然而在现实生活中，视频产品保护更加重要．视频水印除了满足图像水印的一般特性之外，还必须满足实时特性．因此视频水印的嵌入和提取算法必须有较低的计算复杂性．本文提出一种用于视频产品完整性认证的位域实时视频水印的算法．实验表明，该算法有较高的视觉质量，同时能对修改进行准确定位．满足完整性认证水印要求．

Real-Time Video Watermarking Algorithm in the Bit Domain

Under the present watermarking algorithm,image watermarking algorithms are far more than videos'.But in the real world,protection of video is more significant.Besides general requirements to be satisfied like image watermarking,video watermarking must take real-time property into account.So a video watermarking embedding and detection algorithm must have low computational complexity.This paper proposes a real time watermarking algorithm in the bit domain for complete authentication.Experimental results show that this algorithm has high visual quality,at the same time,can exactly localize the alteration,and really satisfies the requirement of complete authentication.
