Abstract :
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) scheme is also proposed in detail. Finally, the good performance can be seen in experimental results.
