Robust video watermarking based on 3D-DWT domain

The digital watermarks have recently been recognized as a solution for protecting the copyright of the digital multimedia. In this paper a novel DWT-based video watermarking algorithm is proposed based on a three-level DWT using Haar filter which is robust against geometric distortions such as Downscaling, Cropping, and Rotation. It is also robust against Image processing attacks such as low pass filtering (LPF), Median filtering, and Weiner filtering. Furthermore, the algorithm is robust against Noise attacks such as Gaussian noise, Salt and Pepper attacks. The embedded data rate is high and robust. The experimental results show that the embedded watermark is robust and invisible. The watermark was successfully extracted from the video after various attacks.
