Some voxels are marked as FGT, but should be they included at all?  They could be fairly easily excluded by demanding that the FGT+FAT is a Connected object and does not consist of the several
disconnected components. This should be true for Phantom and Human data?
"EdgeWave MultiLabel - Boundary Only" variant was implemented.  Only the boundary voxels of the total region are modified by Multilabel Peel\Grow.
Provides slightly different result

FGT=187.8 cm3, FAT = 944, Total = 1131.8, Fgt%=16.5%


Implemented new algorithm "EdgeWave MultiLabel". This is a general algorithm: given an initial segmentation of the region with multiple labels it applies EdgeWave morphological criteria to correct these regions while completely covering the total region.

This was applied to p1s0_L example that had issues with partial volume voxels being misclassified as FGT.

This algorithm contains both internal and external morphological competition.  So additional algorithm "EdgeWave ML Boundary" will be attempted.


FGT: 180.23, FAT=950, total=1130.23,  FGT percentage=15.9%

Implemented the original variant of the FGT breast workflow.  It consists of BiCal, Bimodal Laplace thresholding.  While providing great (+-4% ground truth) result for some images, other images are problematic. This requires to develop an additional Morphological module, as none of the existing variants of EdgeWave don't seem to fit.
