Block-based Tchebichef image watermarking scheme using psychovisual threshold

Digital multimedia has drastically increased the production and distribution of digital data in the recent years. Unauthorized manipulation and ownership of digital image have become a serious issue. In this paper, we propose a watermarking scheme which uses block-based Tchebichef moments considerin...
