Abstract

On a finite sublattice .4 of Z’, consider a free-boundary Ising model X with inverse temperature p > 0 and without external field. Assume that each spin is flipped with unknown probability E, independently for each site and of X. This has been suggested as a stochastic model for digital images. In this paper estimators are proposed for p and F and shown to be consistent as .I T Z*. They are very easily computable since they do not require any evaluation of conditional statistics. Numerical experiments are reported on the performance of these statistics on a lattice of moderate size.
