SelectiveClosing3d

Closes objects of a three-dimensional binary image conditionally to a local constraint.

Access to parameter description

For an introduction: This algorithm successively runs a SelectiveDilation2d and a SelectiveErosion2d with the same kernel and threshold.
It can be applied only on binary images. Using a threshold of 1 amounts to applying a standard morphological closing.
This operator is smoother than the classic closing, and softens the appearance of the structuring element in the filtered image.
