Description of the directories
  1. MEXfiles  MATLAB has the capability of running functions written in C. The files which hold the source for these functions are called MEX-Files.
    Some functions of our codes are written in C. This is typically the case of functions for sampling a Markov field with given stationary distribution.
  2. Pictures  This directory contains the synthetic and real images, used in the paper. For synthetic images called pict, three dat-files are available: pict_true.dat, pict_obs.dat and pict_init.dat that contain resp. the true image, the observed image (additive gaussian noise) and the initial image for the iterative algorithms. For real images, only two dat-files are available: pict_obs.dat and pict_init.dat.
  3. CodesMCVEM This directory contains the codes for running MCVEM. The main file is InterfaceMCVEM.m, where the different parameters and the different choices of implementation are fixed.
Example
The MATLAB-function ExampleMCVEM contains examples of call of the function MCVEM. This function in turn calls InterfaceMCVEM.m and creates an output file.
