Review of Different Embedding Factor's for an Adaptive Image Watermarking Scheme

Digital image watermarking is one of the most important techniques for copyright protection. The robustness, imperceptibility and capacity are the basic requirements of digital image watermarking. The key factor that affects both the robustness and imperceptibility is the embedding factor. In particular, the concept robustness and imperceptibility image watermarking is reviewed in details. In this paper, review different method to determine the watermark strength. And, a novel adaptive methodology is introduced to estimate watermark strength to ameliorate both imperceptibility and robustness at the same time.
