Blind wavelet-based watermarking scheme using fuzzy clustering theory

In this paper, we propose an image adaptive watermarking scheme in DWT domain, by utilizing fuzzy clustering theory, the watermark can be adaptively embedded without degradation of the original image. In order to improve the robustness, we embedded watermark several times, and watermark can be extracted without referring to the original image. Simulations of various attacks will be given to demonstrate the robustness of the proposed algorithm.
