A reversible, ergodic, Markov process taking values in the space of polygonally segmented images is constructed. The stationary distribution of this process can be made to correspond to a Gibbs-type distribution for polygonal random fields introduced by Arak and Surgailis and a few variants thereof, such as those arising in Bayesian analysis of such random fields. Extensions to generalized poly...
