Abstract |
|
Digital watermarking is an evolving field that requires continuous effort to find the best possible method in protecting multimedia content. Digital watermarking is the procedure whereby secret information (the watermark) is embedded into the host multimedia content, such that it is hidden, i.e., not perceptually visible. Besides this, information should be recoverable, even if content is degraded by different attacks. The two basic requirements for an effective watermarking scheme, imperceptibility (PSNR) and robustness (NCC), conflict with each other. For optimum PSNR and NCC, optimization techniques are used which includes Genetic algorithm, Hill and climb search, Tabu algorithm, Simulated Annealing etc. Here review of different optimization techniques for watermarking is presented. |
