Adaptive image watermarking using bidimensional empirical mode decomposition

Digital watermarking is considered one of the technological means used to guarantee security and authenticity data transmitted over communication systems. A new method image using bidimensional empirical mode decomposition (BEMD) will be presented in this article, where idea use BEMD both cover watermark image. The embedding process consists adding each intrinsic modal function (IMF) corresponding IMF watermarked contains three different watermarks appropriate frequencies, which makes it more robust. We for two reasons: first, conserve constituent characteristics second, ensure invisibility watermark. results obtained showed a good response against kinds attacks. This technique has been compared with other methods based on BEMD, results.
