So the main idea of the tool is similar to the thresholding voxel QC tool - it can easy adjust the inclusion stickout. The difference is in the shape of the resulting border of inclusion. Morphology doesn't take into account the transparency of the inclusion and can increase inclusion volume to the area, where you cannot see anything resembling inclusion. As for thresholding tool, it cannot increase inclusion volume to transparent area. Also morphology increase its volume uniformly in all directions, thresholding tool - the increase depends on inclusion transparency.
So you can apply morphology tool for inclusions with transparent parts. Also multiple application of this tool is useful if you want to remove small transparent holes in inclusion or split big inclusion from other, connected by thin necks. This techniques are for PRO users and described in chapter "Practically important cases".
