SAR IMAGE CHANGE DETECTION BASED ON FUZZY MARKOV RANDOM FIELD MODEL
SAR change detection Markov random field fuzzy set theory
2018/5/16
Most existing SAR image change detection algorithms only consider single pixel information of different images, and not consider the spatial dependencies of image pixels. So the change detection resul...
WATERBODIES EXTRACTION FROM LANDSAT8-OLI IMAGERY USING AWATER INDEXS-GUIED STOCHASTIC FULLY-CONNECTED CONDITIONAL RANDOM FIELD MODEL AND THE SUPPORT VECTOR MACHINE
Water index CRF Landsa Water extraction SVM
2018/5/15
One of the most important applications of remote sensing classification is water extraction. The water index (WI) based on Landsat images is one of the most common ways to distinguish water bodies fro...
Numerical study of the three-dimensional random-field Ising model at zero and positive temperature
Three-dimensional ising model zero temperature heat capacity critical point
2014/12/20
In this paper the three-dimensional random-field Ising model is studied at both zero temperature and positive temperature. Critical exponents are extracted at zero temperature by finite size scaling a...
Moderate deviations for random field Curie-Weiss models
Random field Curie-Weiss model disordered mean-field moderate deviations large deviations transfer principle
2012/6/21
The random field Curie-Weiss model is derived from the classical Curie-Weiss model by replacing the deterministic global magnetic field by random local magnetic fields. This opens up a new and interes...
A geometric derivation of the linear Boltzmann equation for a particle interacting with a Gaussian random field
Processes in random environments Quantum field theory Coherent states Kinetic theory of gases
2011/8/25
Abstract: The linear Boltzmann equation is derived from a microscopic quantum model of a particle interacting, in the weak coupling limit, with a translation invariant and centered Gaussian random fie...
Critical behavior of the Random-Field Ising Magnet with long range correlated disorder
random- eld Ising model, correlated disorder, corrections to scaling
2011/9/29
We study the correlated-disorder driven zero-temperature phase transition of the Random-Field Ising Magnet using exact numerical ground-state calculations for cubic lattices. We consider correlations ...
A time-dependent Poisson random field model for polymorphism within and between two related biological species
A time-dependent Poisson random field model polymorphism biological species
2010/11/12
We derive a Poisson random field model for population site polymorphisms differences within and between two species that share a relatively recent common ancestor. The model can be either equilibrium ...
Scaling and self-averaging in the three-dimensional random-field Ising model
Scaling self-averaging three-dimensional random-field Ising model
2010/11/25
We investigate, by means of extensive Monte Carlo simulations, the magnetic critical behavior of the three-dimensional bimodal random-field Ising model at the strong disorder regime.We present results...
Fat-tailed and compact random-field Ising models on cubic lattices
Random-Field Ising Model Fat tails Compact distributions
2010/11/23
Using a single functional form which is able to represent several different classes of
statistical distributions, we introduce a preliminary study of the ferromagnetic Ising model
on the cubic latti...
On Random Field Induced Ordering in the Classical XY Model
Random Field Induced Ordering Classical XY Model
2010/12/13
Consider the classical XY model in a weak random external field pointing along the Y axis with strength . We study the behavior of this model as the range of the interaction is varied.
We prove that...
