R package bayesImageS

March 4, 2015

My R package, bayesImageS version 0.1-21, is now available online. It uses a hidden Potts model with additive Gaussian noise for image segmentation of 2D and 3D datasets. The latent labels z can be simulated using chequerboard updating or the Swendsen-Wang algorithm. Several methods for full Bayesian inference with intractable likelihoods are supported, including pseudolikelihood, the exchange algorithm, path sampling, and approximate Bayesian computation (ABC-MCMC & ABC-SMC).

The R source package is released under the GNU General Public License, version 2. Its computational engine is implemented in C++ using RcppArmadillo and OpenMP. There is zero documentation available at present, but I’m working on that…
