چکیده
-------------------------------------------------------Abstract----------------------------------------------------------Digital watermarking is process of embedding information into a digital signal which is used to know about its authencity or identity of its owners and producers in the same manner as document having a bench mark for visible identification. This paper presents an innovative watermarking scheme based on biogeography based optimization in transform domain. The proposed approach is robust against watermarking attacks. Also, the watermarked image quality is considered. Simulation results also show both robustness and image quality with bbo.
