==Module Description==
This module implements a local intensity correction for inhomogeneities due to coil placement in cardiac LGE-MRI images.  It fits a gradient function to the image data and normalizes accordingly.  Note that this is not a whole image correction and it is specific to LGE MRI cardiac images.  The input to this module is a segmented region on which to base the intensity gradient model and a segmentation of the region of interest to apply the correction.  There are no parameters.
