Various algorithms for 3D Mathematical Morphology.
3D mathematical operations (erosion, dilatation, …) 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 is available that takes into account the calibration of the image stack. A 3D normalized dsitance 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 performs closing on individual objects, hence avoiding objects to touch during dilatation operation.
For details go to the 3D ImageJ Suite.
