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...
Multifractal analysis of some multiple ergodic averages for the systems with non-constant Lyapunov exponents
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...

A modification of the method for determination of surface fractal dimension and multifractal analysis
Computer Assistance in the engineering tasks and scientific research Fractal dimension Multifractal spectrum
2009/12/14
Purpose: In this work modification of the PCM method for determination of the surface fractal dimension is proposed. Complete reasoning, leading to correct formula for determination Ai(δ) is presented...
Organisation of joints and faults from 1-cm to 100-km scales revealed by optimized anisotropic wavelet coefficient method and multifractal analysis
Organisation of joints and faults wavelet coefficient method multifractal analysis
2009/11/16
The classical method of statistical physics deduces the macroscopic behaviour of a system from the organization and interactions of its microscopical constituents. This kind of problem can often be so...
Multifractal analysis for the ULF geomagnetic data during the 1993 Guam earthquake
Multifractal analysis ULF geomagnetic data Guam earthquake
2009/11/9
In our previous papers we have shown that the fractal (monofractal) dimension (Do) showed a significant increase before the Guam earthquake occurred on 8 August, 1993. In order to have a further suppo...
Representative elementary area for multifractal analysis of soil porosity using entropy dimension
Representative elementary area multifractal analysis soil porosity entropy dimension
2009/11/3
The notion of representative elementary area (REA) developed to address heterogeneity and scale problems in quantitative soil pedology comes from the notion of representative elementary volume of flui...
Assessing soil surface roughness decay during simulated rainfall by multifractal analysis
soil surface roughness decay simulated rainfall multifractal analysis
2009/11/2
Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topogra...
Multifractal analysis and instability index of prior-to-crash market situations
Multifractal analysis instability index prior-to-crash market situations
2010/11/2
We take prior-to-crash market prices (NASDAQ, Dow Jones Indus-trial Average) as a signal, a function of time, we project these discrete values onto a vertical axis, thus obtaining a Cantordust. We stu...
Long-term correlations and multifractal analysis of trading volumes for Chinese stocks
Econophysics Trading volume Intraday pattern Correlation Multifractality
2010/10/29
We investigate the temporal correlations and multifractal nature of trading volume of 22
liquid stocks traded on the Shenzhen Stock Exchange in 2003. We find that the trading
volume exhibits size-de...
