Bayesian methods for segmentation of 2D and 3D images, such as computed tomography and satellite remote sensing. This package implements image analysis using the hidden Potts model with external field prior. Latent 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 (ABC-MCMC and ABC-SMC).
