A Fractal Watermarking Scheme for Image in DWT Domain
Shuguo Yang, Chunxia Li, Sun Sheng-he, Rongsheng Xie · 2007
The scheme in this paper carries out embedding and detecting of watermarking by the fractal technology in DWT domain. This method introduces the threshold control, searches for the self-similar domain subtrees by the fractal transforms and let the domain subtrees to be the watermarking embedding trees. The watermarking signals are embedded and detected according to the JND model. A large number of attacking experiments prove that security and the robustness of the method.
