摘要
文章针对目前现有的基于小波变换和奇异值分解相结合的数字水印算法存在的缺陷,提出了一种新的视频水印算法:以二值图像为水印的混合整数小波变换和奇异值分解的视频水印盲提取算法,重点论述了奇异值分解的视频水印嵌入与检测以及安全性的测试。实验表明,提出的新算法具有较好的高透明性和鲁棒性。
To dealing with the weak point of current algorithm which combines the wavelet transform and singular value decomposition, a new and improved digital video watermarking algorithm is offered: binary image as a watermark to the mixed-integer wavelet transform and singular value decomposition of the blind video watermarking extraction algorithm. We focus on the singular value decomposition of the video watermark embedding and detection, and security test; experiments show that the new proposed algorithm has higher transparency and better robustness on anti-attack than else.
