Upcrossings of Random Fields

Advances in Applied Probability, 1978
is of great importance in many applications. For example, if we consider a geographical map and denote height by X(t) where t is the set of geographical coordinates, Z(S) is the height of the highest mountain in the area S. In general, it is not possible to make any exact useful statements about the distribution of Z(S), and one must have recourse to ...

Dynamic Markov Random Fields

2008 International Machine Vision and Image Processing Conference, 2008
In this talk the author will outline some of the recent work undertaken by the Oxford Brookes Vision Group, a common theme underlying much of the research is to cast vision problems in terms of combinatorial optimization which provides a rich a deep theory for understanding them, with many new and exciting results.

Random fields on random graphs

Advances in Applied Probability, 1992
The distribution (1) used previously by the author to represent polymerisation of several types of unit also prescribes quite general statistics for a random field on a random graph. One has the integral expression (3) for its partition function, but the multiple complex form of the integral makes the nature of the expected saddlepoint evaluation in ...

Random Processes and Random Fields

2009
Overview: Because the open channel through which we propagate electromagnetic radiation is often considered a turbulent medium, we present a brief review in this chapter of the main ideas associated with a random field, which in general is a function of a vector spatial variable R and time t.
