Query: HMRF-EM-image: Implementation of the Hidden Markov Random Field Model
  and its Expectation-Maximization Algorithm   In this project, we study the hidden Markov random field (HMRF) model and its
expectation-maximization (EM) algorithm. We implement a MATLAB toolbox named
HMRF-EM-image for 2D image segmentation using the HMRF-EM framework. This
toolbox also implements edge-prior-preserving image segmentation, and can be
easily reconfigured for other problems, such as 3D image segmentation.
