| 摘 要： | 该文基于小波变换特性，根据物体的运动和视频信号内容的纹理复杂度，将小波系数进行分类，根据分类结果并利用相邻帧的统计特性，将水印嵌入小波的低频子带中。仿真实验结果表明该视频水印嵌入算法对于多种攻击，如MPEG压缩编码、丢帧和帧重组等具有很好的稳健性。

| Abstract: | In this paper, an adaptive video watermarking algorithm based on wavelet domain is proposed. The article proposes to classify the wavelet coefficients based on the motion of the objects and the texture complexity of the contents in the video sequence. The experimental results show that the proposed watermarking algorithm is robust to video degradation and distortions, e.g. additive Gaussian noise, MPEG coding at high compression - ratio, frame drop, swap. |
