SAR IMAGE CHANGE DETECTION BASED ON FUZZY MARKOV RANDOM FIELD MODEL [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Most existing SAR image change detection algorithms only consider single pixel information of different images, and not consider the spatial dependencies of image pixels.

Fuzzy Active Contour Model With Markov Random Field for Change Detection

open access: yesIEEE Access, 2022
The traditional active contour models are sensitive to the speckle noise in the synthetic aperture radar (SAR) images. In this paper, the Markov random field (MRF) theory is incorporated into the fuzzy active contour model to detect the changes of ...

Saliency Map Estimation Using a Pixel-Pairwise-Based Unsupervised Markov Random Field Model

open access: yesMathematics, 2023
This work presents a Bayesian statistical approach to the saliency map estimation problem. More specifically, we formalize the saliency map estimation issue in the fully automatic Markovian framework.

Hidden Markov Random Field for Multi-Agent Optimal Decision in Top-Coal Caving

open access: yesIEEE Access, 2020
Applying model-based learning for the optimal decision of the multi-agent system is not trivial due to the expensive price or even the impossibility of obtaining the ground truth for training the model of the complex environment.

Computing the Cramer-Rao bound of Markov random field parameters: Application to the Ising and the Potts models [PDF]

open access: yes, 2013
This report considers the problem of computing the Cramer-Rao bound for the parameters of a Markov random field. Computation of the exact bound is not feasible for most fields of interest because their likelihoods are intractable and have intractable ...
