Abstract
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 transformation, we can retrieve the information embedded into the original image. In the watermarking scheme, the original collage map is altered to embed the watermark into the wavelet domain. Experiments show that the watermarking method is robust against image compression attack
