Abstract
In this paper, we propose an SVD-based watermarking scheme in complex wavelet domain for color video. Video watermarking is well known as the process of embedding copyright information in video bit streams. It has been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video. In this study, an effective, robust and imperceptible video watermarking algorithm is proposed. This algorithm was based on a cascade of two powerful mathematical transforms; the 2-level Dual Tree Complex Wavelet Transform (DT-CWT) and Singular Value Decomposition (SVD). This hybrid technique shows high level of security and different levels of robustness against attacks. The proposed algorithm was tested for imperceptibility and robustness and excellent results were obtained. We compared our proposed algorithm with DWT-SVD based scheme and showed that it is considerably more robust and effective.
