In recent years many methods for image watermarking have been proposed to overcome the growing concern of copyright protection. The goal of all these methods is to satisfy the tradeoff between two important characteristics of robustness and imperceptibility. In this paper an adaptive blind watermarking method in the Contourlet transform domain is proposed. In this method we apply a two-level Contourlet transform on the original image. The first level approximate image is partitioned into blocks. Using a novel edge detection algorithm, important edges of each block of the approximate image are detected and the entropy of each block is also computed. Then by conca...
