Properties of the one-sided model of a Markov random field can be configured using a Markov matrix of Correspondence to: ...
The crucial advantage of this model among other things is that it allows us to restore numerically a posteriori distributions of hidden classes of a Markov random field. ...
As a result, we proposed the adjusted one-sided Markov model of a random field based on the model of a hidden Markov chains. ...

Since the 1970s, there has been increasing interest in the use of Markov Random Fields (MRFs) as models to aid in the segmentation of noisy or degraded digital images. ...
MRFs can make up for deficiencies in observed information by adding a-priori knowledge to the image interpretation process in the form of models of spatial interaction between neighbouring pixels. ...
Extended-Markov Random Fields (E-MRFs) provide a probabilistic framework for combining observed image data with expectations of that data, based on additional knowledge or prediction, during image segmentation ...
