Sinusoidal Signals Pattern Based Robust Video Watermarking in the 3D-CWT Domain
Cheng Dan Deng, Jie Li, Meng Jia, Xinbo Gao · 2009
This paper presents a robust video watermarking scheme. It mainly contains three characteristics: 1) the sinusoidal signals pattern is embedded as watermark in the selected sub-bands of 3D dual-tree complex wavelet transform (3D-CWT), which is employed to preserve the image quality and improve the robustness of watermark; 2) at the detection end, the detected peaks response are used to achieve attacks estimation and rectification; and 3) the watermark is confirmed simply and objectively by detecting the prominent peaks in frequency domain. Experimental results conducted on several popular true color video sequences demonstrate that the proposed watermarking scheme has good performance in terms of common video operations as well as geometric distortions.
