3D Mathematical Morphology
Various algorithms for 3D Mathematical Morphology, as part of the 3D ImageJ Suite.
3D mathematical operations (erosion, dilation, …) are available in 3D Filters using minimum and maximum filters.
A 3D Fill Holes is available, works the same way as in 2D but will not fill holes if it is not closed in the Z dimension.
A 3D Euclidean Distance Map (also called EDT) is available that takes into account the calibration of the image stack. A 3D normalized distance map (called Eroded Volume Fraction, or EVF) is also available.

In the case of labelled objects (as count masks) a Binary Close Labels is available, that permits to perform closing on individual objects, hence avoiding objects to touch during the dilation operation.
