WAVELET DECOMPOSITION OF HYPERSPECTRAL REFLECTANCE DATA FOR QUANTIFYING PHOTOSYNTHETIC PIGMENT CONCENTRATIONS IN VEGETATION
Remote Sensing Vegetation Hyper spectral Analytical Experiment
2015/7/29
The dynamics of pigment concentrations are related to vegetation photosynthetic potential and hence primary production, nutrient
status, stress physiology and plant-environment interactions. Therefo...
BAYESIAN-BASED DESPECKLING IN WAVELET DOMAIN USING “A TROUS” ALGORITHM
Transformation Estimation SAR, Radar Statistics Multiresolution.
2015/7/29
In this paper an improved speckle noise reduction method is presented based on wavelet transform. A 2D Gaussian function is found
to be the best model fitted to the speckle noise pattern cross-secti...
A spatio-temporal Gaussian-Conical wavelet with high aperture selectivity for motion and speed analysis
Extraction of motion parameters speed tuning continuous wavelet transform directional and conical wavelets
2012/5/25
The construction of a spatio-temporal wavelet and its tuning to speed was first realized in the 90s on the Morlet wavelet by M. Duval-Destin \cite{Duval-Destin91a,Duval-Destin92}. This enabled to demo...
Arbitrary-order Hilbert spectral analysis for time series possessing scaling statistics: a comparison study with detrended fluctuation analysis and wavelet leaders
Arbitrary-order Hilbert spectral analysis time series wavelet leaders
2011/8/5
Abstract: In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series dir...
Probing Tissue Multifractality Using Wavelet based Multifractal Detrended Fluctuation Analysis: Applications in Precancer Detection
Fractal Multifractal detrended fluctuation analysis Phase contrast imaging Refractive index Cancer diagnosis
2011/8/4
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...
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...
Cross wavelet analysis:significance testing and pitfalls
Cross wavelet analysis significance testing pitfalls
2009/11/11
In this paper, we present a detailed evaluation of cross wavelet analysis of bivariate time series. We develop a statistical test for zero wavelet coherency based on Monte Carlo simulations. If at lea...
Bayesian modeling and significant features exploration in wavelet power spectra
Bayesian modeling significant features exploration wavelet power spectra
2009/11/2
This study proposes and justifies a Bayesian approach to modeling wavelet coefficients and finding statistically significant features in wavelet power spectra. The approach utilizes ideas elaborated i...
Improved preservation of autocorrelative structure in surrogate data using an initial wavelet step
preservation autocorrelative structure surrogate data initial wavelet step
2009/11/2
Surrogate data generation algorithms are useful for hypothesis testing or for generating realisations of a process for data extension or modelling purposes. This paper tests a well known surrogate dat...
Quantum computation of multifractal exponents through the quantum wavelet transform
Quantum computation multifractal exponents quantum wavelet transform
2010/4/7
We study the use of the quantum wavelet transform to extract efficiently information about the multifractal exponents for multifractal quantum states. We show that, combined with quantum simulation al...
