Digital Video Watermarking with a Genetic Algorithm
Pik-Wah Chan, Michael Rung-Tsong Lyu · 2005
Abstract. Due to the explosion of data exchange on the Internet and the extensive use of digital media, it has been of intense interest to digital data owners in multimedia security and multimedia copyright protection. In this paper, a comprehensive approach for protecting and managing video copyrights with watermarking techniques is introduced. We propose a novel digital video watermarking scheme based on the scene change analysis and genetic algorithm. Robustness and fidelity are the essential requirements of a successful watermarking scheme. In pervious work, a robustness scene-based watermarking scheme is proposed. We focus on improving the fidelity of the scheme in this paper. The fidelity of the scheme is enhanced by applying a genetic algorithm, which optimizes the quality of the watermarked video. The effectiveness of this scheme is verified through a series of experiments. 1
