Huifen Huang · Packaging Engineering · 2010
Fractal and wavelet combined robust digital watermarking algorithm was put forward to improve the robustness of image watermarking algorithm.This algorithm transformed the watermarking information into self-similar fractal image;and it discreted the host image through Haar wavelet transformation,and then embed the fractal binary watermarking image into Haar wavelet low-frequency band.The simulation experiments prove that this algorithm has good robustness to noise,JPEG compress,cutting,smoothing filtering and other image distortion processing.
