a Markov random field (MRF) model, ie the Ising case, in the task of image segmentation.
The LCE algorithm makes efficient use of the local information in the image, avoiding the
exclusion of certain blocks as in the least square (LSQR) algorithm. In addition, LCE doesn't
require complex matrix computations, therefore reduces the computational cost. As a
general algorithm, LCE can be used to estimate the prior parameters in anisotropic label …
