| Abstract: | A digital watermarkingg technique thai combines fraetal ending and wavelet transformation is proposed, using for reference the wavelet - based watermarking algorithm and the theory of fractal image compression and comhined with wavelet - zero trees coding, The technique makes full use of the respective advantages of the wavelet - zero trees, the wavelet transfnrmatinn and fractal coding to improve the quality of the watermarking images and boost up the robustness of the watermarking. |
