A method for segmenting a digitized image includes providing a digitized image comprising a plurality of intensities defined on a lattice of pixels, initializing (22) a Bayesian prior probability and likelihood function for segmenting said image, decomposing (23) said image into a union of a plurality of subspaces wherein each subspace is a product of k-partitions, and distributing a plurality Bayesian posterior probability functions over said subspaces, updating (25) said Bayesian posterior probability functions via a data-driven Markov-chain, and selecting (27) a subset of said Bayesian posterior probability functions that approximate a true Bayesian posterior probability function. |
