Research on Digital Watermarking Algorithm Based on Fractal in DCT Domain
Cui Han · Modern Computer · 2007
Proposes a fractal watermarking algorithm,it improve the traditional fractal digital watermarking,applies chaotic sequence transform to the watermark sequence,enhances the robustness.Experimental results show that the algorithm not only has good robustness,but also resists some kinds of transform such as Gaussian noise and clipping.
