متن کاملWavelet leaders in multifractal analysis
The properties of several multifractal formalisms based on wavelet coefficients are compared from both mathematical and numerical points of view. When it is based directly on wavelet coefficients, the multifractal formalism is shown to yield, at best, the increasing part of the weak scaling exponent spectrum. The formalism has to be based on new multiresolution quantities, the wavelet leaders, ...
متن کاملWavelet-based Multifractal Analysis of RR Time Series
In this paper are presented the current results of scientific research of the RR time series for healthy and unhealthy subjects. TheRR intervals are obtained from 24-hour digital Holter ECG records of subjects. The used in the presented research work wavelet-based multifractal analysis of RR time series is provided by Wavelet Transform Modulus Maxima method. This method is based on wavelet anal...
متن کاملWavelet-based multifractal analysis of fMRI time series.
Functional magnetic resonance imaging (fMRI) time series are investigated with a multifractal method based on the Wavelet Modulus Maxima (WTMM) method to extract local singularity ("fractal") exponents. The spectrum of singularity exponents of each fMRI time series is quantified by spectral characteristics including its maximum and the corresponding dimension. We found that the range of Hölder ...
متن کاملWavelet-based multifractal analysis of laser biopsy imagery
In this work, we report a wavelet based multi-fractal study of images of dysplastic and neoplastic HEstained human cervical tissues captured in the transmission mode when illuminated by a laser light (He-Ne 632.8nm laser). It is well known that the morphological changes occurring during the progression of diseases like cancer manifest in their optical properties which can be probed for differen...
