Robust Digital Watermarking Algorithm on Combination of Fractal and Wavelet

Abstract:

To improve the robustness of watermarking algorithms, this paper proposes a robust digital watermarking algorithm based on combination of fractal and wavelet. By key the algorithm transfers watermark information into self-similar fractal images, discretes Haar wavelet to host image, and embeds two fractal watermark image after fractal into Haar wavelet sub-band. Simulation results show that the algorithm has good robustness to image distortion as noise, JPEG compression, shear, filtering, etc.
