摘　　要：结合离散小波变换(DWT)和舒尔(Schur)分解的特点,提出一种离散小波变换和实舒尔分解结合的全盲数字视频水印算法。由于使用了离散小波变换,盲特性较高,水印视频嵌入后没有可见的失真现象;又由于舒尔分解与其他变换相比具有更少的计算量,所以水印处理的效率更高。仿真实验结果表明:所提出算法对噪声攻击和视频攻击都具有较强的鲁棒性。Combined with discrete wavelet transform(DWT)and Schur decomposition characteristics,a kind of total blind digital video watermarking algorithm based on DWT-Schur combination is proposed.By using discrete wavelet transform,blind featureofthe scheme is very high and after there is no visible distortion after the watermark video is embedded.Since Schur decomposition compared with other transformation has less amount of calculation,the watermark processing is more efficient.The simulation results proved that this technology for the noise attack and videoattack has very strong robustness.
