| Abstract(in English) | This report deals with the decomposition of surface data into several fractal signal based on the parameter estimation by the Importance Sampling (IS). Assuming the models for generating the surface, the likelihood function is defined and the parameter are estimated based on the mean likelihood by using the IS. The approximation of the wavelet coefficients is used for estimation as well as the statistics defined for the variances of wavelet coefficients, and the likelihood function is modified by the approximation. After completing the decomposition of underlying surface data into several fractal surface, the prediction method for the fractal signal is employed based on the scale expansion. |
