We present a novel technique for the digital watermarking of still images based on fractal encoding and decoding. In general, a fractal coder exploits the spatial redundancy within the image by establishing a relationship between its different parts.

Some influential fractal methods are first discussed in this paper. Then a dual-classification technique is used to optimize the same-sized block mapping scheme, leading to considerable speed-up with no loss in fidelity. The process of our FX(HX) sch
