Separating And Filling

Algorithms that improve segmentation by filling some area or separating connected objects.

FillHoles2d: Fills the holes inside particles of a two-dimensional binary image.
FillHoles3d: Fills the holes inside particles of a three-dimensional binary image.
RemoveSmallHoles: Fills the smallest holes of a binary image.
FillImageBorder3d: Fills holes of border faces of a three-dimensional binary image.
ExpandLabelBoundaries: Performs a constrained dilation around objects of a label image.
SeparateObjects: Separates connected objects in a binary image.
HExtremaWatershed: Computes the watershed lines of a grayscale image.
SeparateObjectsByBlock: Separates connected objects in a binary image in a low memory consumption mode.
HExtremaWatershedByBlock: Computes the watershed lines of a grayscale image in a low memory consumption mode.
ConvexHull2d: Fills the concavities of particles in a two-dimensional binary image.

The Separating and Filling group contains algorithms helpful for improving a segmentation by filling an object's hollow areas (enclosed or open) or by separating objects that touch each other.
