摘要
Given a graph of a fractal interpolation function f which is the attractor of an unknown IFS with affine constration maps w1 ,w2 ,… ,wN ,the maps wi(i= 1,2,… ,N)are found based on the self-similarity of the zero-crossing points of wavelet transform. The effectiveness of method is shown in an example.
