Fractal model of a one-dimensional discrete signal and its implementation
Xin Zhu · IEE Proceedings - Vision Image and Signal Processing · 1994
An extended iterated-function-system (IFS) interpolation method is presented for modelling for a given discrete signal. To reduce the computing complexity a suboptimal search algorithm with a robust technique for estimating the IFS affine-map parameters is introduced. Simulation results show that the IFS approach achieves a higher signal-to-noise ratio than does an existing approach based on autoregressive modelling.
