MULTIFRACTAL PROPERTIES OF THE SETS OF ZEROES OF BROWNIAN PATHS
independent random variables Brownian motion local time Hausdor
2015/9/29
In this paper we study Brownian zeroes in the neighborhood of which one can observe non-typical growth
rate of Brownian excursions. We interprete the multifractal curve for the Brownian zeroes calcul...
VERY HIGH SPATIAL RESOLUTION IMAGE SEGMENTATION BASED ON THE MULTIFRACTAL ANALYSIS
Remote Sensing Vision Analysis Algorithms Texture Segmentation High Resolution Multifractal CDROM
2015/7/29
The availability of very high spatial resolution images in remote sensing brings the texture segmentation of images to a higher level
of complexity. Such images have so many details that the classic...
EDGE-PRESERVING SMOOTHING OF HIGH-RESOLUTION IMAGES WITH A PARTIAL MULTIFRACTAL RECONSTRUCTION SCHEME
Remote Sensing, Segmentation High-Resolution
2015/6/1
We introduce a novel approach as a preprocessing step for
feature extraction and/or image segmentation. The method is derived from the multifractal formalism proposed for image
compression. This pro...

Multifractal analysis of some multiple ergodic averages non-constant Lyapunov exponents Dynamical Systems
2012/6/27
We study certain multiple ergodic averages of an iterated functions system generated by two contractions on the unit interval. By using the dynamical coding ${0,1}^{\mathbb{N}}$ of the attractor, we c...

2012/4/20
We suggest a simple explanation of the difference between transverse and longitudinal scaling exponents observed in experiments and simulations. Based on the Vortex filament model and Multifractal con...

Abstract: The refractive index fluctuations in the connective tissue layer (stroma) of human cervical tissues having different grades of precancers (dysplasia) was quantified using a wavelet-based mul...
Perturbation approach to multifractal dimensions for certain critical random matrix ensembles
multifractal dimensions Perturbation random matrix ensembles
2011/7/6
Fractal dimensions of eigenfunctions for various critical random matrix ensembles are investigated in perturbation series in the regimes of strong and weak multifractality. In both regimes we obtain e...
Computational approach to multifractal music
Fractal, Fractal dimension, Mulifractality, Singularity spectrum
2011/9/1
In this work we perform a fractal analysis of 160 pieces of music belonging to six different genres. We show that the majority of the pieces reveal characteristics that allow us to classify them as ph...
