| 摘 要： | 视频水印技术是保护数字视频版权的一种有效方法。提出一种基于3DDWT的彩色视频水印算法,按场景以16帧划分视频,在各子段YCbCr颜色空间上对Y分量进行二级三维小波变换,利用三维小波低频帧间系数相近而不相同的特性进行水印嵌入,并实现了水印的盲提取。实验结果表明,该算法在保证含水印视频图像质量的同时具备良好的鲁棒性,对各种视频几何攻击及MPEG压缩均具有较强的抵抗能力。

| Abstract: | Video watermarking technology is an efficient method to protect the copyright of digital video.A color video watermarking algorithm based on 3D DWT is presented.It partitions the video with 16 frames in each scene.The two level and three dimensional wavelet transform is carried out in the Y component of YCbCr color space,and the watermark is embedded in the lowest frequency frames by using the characteristic that the coefficients are close and different.The watermark can be extracted without original video.... |
