Bayesian Multifractal Image Segmentation

open access: yes
Multifractal analysis (MFA) provides a framework for the global characterization of image textures by describing the spatial fluctuations of their local regularity based on the multifractal spectrum. Several works have shown the interest of using MFA for

Multifractal analyses of daily rainfall time series in Pearl River basin of China

open access: yes, 2014
The multifractal properties of daily rainfall time series at the stations in Pearl River basin of China over periods of up to 45 years are examined using the universal multifractal approach based on the multiplicative cascade model and the multifractal ...

Multifractal zeta functions

open access: yes, 2017
Multifractals have during the past 20 − 25 years been the focus of enormous attention in the mathematical literature. Loosely speaking there are two main ingredients in multifractal analysis: the multifractal spectra and the Renyi dimensions.

ОТНОСИТЕЛЬНЫЕ РАЗМЕРНОСТИ РЕНЬИ

open access: yesПроблемы анализа, 2012
Recently, many authors are discussing the use of methods of fractal geometry [5] to compare the distributions of the various measures. However, in practical applications, comparison of distributions by comparing the calculated multifractal spectra can be

Heart rate variability series during physical activity analyzed with multifractal techniques

open access: yesJournal of Physics: Complexity
Our study uses multifractal techniques to analyze time series of heart rate variability series ( RR time series) during rest and physical activity. Subsets of the RR time series data were extracted for each stage.

Log-Euler's gamma multifractal scenario for products of Ornstein-Uhlenbeck type processes

open access: yes, 2008
We investigate the properties of multifractal products of the exponential of Ornstein-Uhlenbeck processes driven by Lévy motion. The conditions on the mean, variance and covariance functions of these processes are interpreted in terms of the moment ...
