| 摘 要： | 提出了一种基于内容的抗线性共谋攻击的视频水印算法.根据图像的视觉特征以及区域DCT系数的关系,选择水印嵌入区域.利用局部JND(just-noticeable distortion)值,得到一种自适应的摹于视觉内容的扩频水印方案.实验结果表明,该水印方案能有效地抵抗第一类和第二类线性共谋攻击,具有较强的顽健性、稳定性和视觉不可见性.

| Abstract: | A content dependent video watermark algorithm for resisting linear collusion attacks was presented. The image's visual features and DCT coefficients of sub-region were utilized to select the watermark embedding locations. Moreover the mechanism of JND(just-noticeable distortion) was used to adjust the embedding strength of proposed algorithm. These components may be then used as building blocks to construct a self-adaptive content dependent spread spectrum watermark solution. Experimental results have been ... |
