bayesImagesS: Bayesian methods for image segmentation using a hidden Potts model

Viewed: 2458

R package, bayesimageS, implements Bayesian image analysis using the hidden Potts model with external field prior. Ltent labels are sampled using chequerboard updating or Swendsen-Wang. Algorithms for the smoothing parameter include pseudolikelihood, path sampling, the exchange algorithm and approximate Bayesian computation. This R package was written during a QUT based PhD, which was a collaborative project between QUT and the Radiation Oncology Mater Centre, Queensland Health titled, Bayesian computational methods for spatial analysis of images. It is an R source package (.tar.gz) containing.R and .cpp (R and C++) source code.
