## Iterated Function System

(graphics)
(IFS) A class of fractals that yield natural-looking forms like ferns or snowflakes. Iterated Function Systems use a very easy transformation that is done recursively.

The fixed point or fixed set (set or point A) in Theorem 3 is called the attractor of this iterated function system. The attractors of the iterated function system are generally fractal or have basic properties of fractal.
Fractal image coding is based on the theory of the partitioned iterated function system (PIFS) [2].
Hence we obtained the set [C.sub.[delta]] as the attractor of the graph directed iterated function systems, defined by the graph, shown in Figure 8.

The method of iterated function systems with greyscale maps (IFSM), as formulated by Forte and Vrscay (1995), can be used to approximate a given element u of [L.sup.2]([0,1]).
If each [w.sub.i] (1 [less than or equal to] i [less than or equal to] m) is a contractive map from X to X, then we call (X, [{[w.sub.i]}.sup.m.sub.i=1]) the contractive iterated function systems (IFS).
In (KigLap93), the authors prove that for a nested fractal the exponent [d.sub.S] of the leading term in the eigenvalue counting function of this Laplacian satisfies [d.sub.S]/2 = ln M/ln(M[??]), where M denotes the number of similitudes in the iterated function system and [??] the energy scaling factor introduced above.

For an infinite iterated function system, by assuming the open set condition, BDP, and that the maps of the IFS are [C.sup.1+[epsilon]] smooth, Mauldin and Urbanski [4] proved that the Hausdorff dimension of the limit set is given by the zero of some topological pressure function.
We give in this paper an expression for the moment matrix associated to a self-similar measure given by an Iterated Function Systems (IFS).
In Section "Iterated function systems" the main results from the IFS theory are briefly recalled.
