摘要：
We propose a new method to determine the multi-affine fractal exponents based on a generalization of the roughness concept. For synthetic multi-affine fractal profiles with exactly known exponents, we show that the results obtained in this method are more accurate than the results obtained with the height-height correlation function method. Also in the present method, scaling is observed using profiles with a number of points more than one order of magnitude smaller.
