一种含边信息的小波域视频水印算法
Video Watermark Algorithm in Wavelet Domain with Side Information
摘要
Abstract
By using side information in flame and between frames, this paper proposes a video watermark algorithm in wavelet domain with side information. In the algorithm, dither modulation is adopted, and the motion feature and texture feature are used as side information to determine the adaptive quantification step of every frame. Experimental results indicate that the algorithm can implement blinding examination and the invisibility is good. It is also robust to the special attacks of video watermark such as Gaussian noise, frame average, frame delete and frame displacement.关键词
