Self-similarity based image watermarking

In this paper we present an original way to mark images. Firstly the different techniques in watermarking are presented. In a second part our approach is outlined. It consists in searching an IFS (Iterated function systems) in the image to hide new similarities in it. In a third part two different algorithms are presented: the first uses the luminance domain, the second uses the DCT (Discrete Cosine Transform) domain. Finally results and perspectives of our scheme are outlined.
