Our paper present a watermarking scheme basing on an insertion of similarities. In a rst part di erent watermarking techniques are presented and classed. In a second part our sche...
A novel digital image watermarking method based on wavelet domain fractal coding is presented in this paper. Employing the invariant parameters of the wavelet domain fractal trans...
We present a new image coding scheme based on an unification of fractal and transform coding. We introduce a generalization of the luminance transformation used by fractal coding ...
Fractal image coding can be seen as spectral prediction of coefficients in the wavelet decomposition of an image. Fine scale coefficients are described by shifted and scaled coeff...

In this paper, we develop a robust bit-plane watermarking technique based on zerotree coding. A robust watermark is an imperceptible but indelible code that can be used for owners...
