摘要：
The digital watermarks have recently been recognized as a solution for protecting the copyright of the digital multimedia. In this paper, a new method for video watermarking with high transparency based on 3D-DWT is proposed. This algorithm is implemented on the basis of Human Vision System (HVS). By using the patchwork methods in Discrete Wavelet Transform (DWT) domain, this algorithm is robust against different attacks such as frame dropping, frame swapping, frame averaging, median filtering and MPEG-2 video encoding. The experimental results show that the embedded watermark is robust and invisible. The watermark was successfully extracted from the video after various attacks.
