Abstract
In the recent years, watermarking algorithms were designed based on different dynamical chaotic systems. In this paper we propose some ideas to improve the performances of this kind of techniques using the PWLCM, the DCT and luminance transformation of the image in order to hide the watermark information in an invisible and robust way.
