On a Parameter Estimation Method for Gibbs-Markov Random Fields

Fig. 2. space by Patrick-Fisher's algorithm (solid line) and E (dotted line). Bayes error estimates for SONAR data transformed to IO-dimensional high-dimensional data these results might be more in favor of E.) This is a result of the fact that each iteration of simplex requires that the samples be transformed to the low-dimensional space, and then the Bayes error estimated in that space, which...

An efficient estimator for Gibbs random fields

An efficient estimator for the expectation R f dP is constructed, where P is a Gibbs random field, and f is a local statistic, i. e. a functional depending on a finite number of coordinates. The estimator coincides with the empirical estimator under the conditions stated in Greenwood and Wefelmeyer [6], and covers the known special cases, namely the von Mises statistic for the i.i.d. underlying...

Gibbs Random Fields, Cooccurrences, and Texture Modeling

Gibbs random eld (GRF) models and co-occurrence statistics are typically considered as separate but useful tools for texture discrimination. In this paper we show an explicit relationship between co-occurrences and a large class of GRF's. This result comes from a new framework based on a set-theoretic concept called the \aura set" and on measures of this set, \aura measures". This framework is ...

Gibbs Random Fields : Temperature and Parameter Analysis

Gibbs random eld (GRF) models work well for synthesizing complex natural-looking image data with a small number of parameters; however, estimation methods for these parameters have a lot of problems. This paper addresses the analysis problem in a new way by examining the role of the temperature parameter of the Gibbs distribution. Studies of the model energy with respect to the temperature are ...

Markov Random Fields and Gibbs Measures

A Markov random field is a name given to a natural generalization of the well known concept of a Markov chain. It arrises by looking at the chain itself as a very simple graph, and ignoring the directionality implied by “time”. A Markov chain can then be seen as a chain graph of stochastic variables, where each variable has the property that it is independent of all the others (the future and p...
