Closing

Class: NodeMaskClosing

Node Icon

Apply the morphological closing operation on a binary mask. The morphological closing of a binary mask \(I\) is defined as the erosion of the silation of the mask: \(\textrm{Closing}\left(I\right) = \textrm{Erosion}\left(\textrm{Dilation}\left(I\right)\right)\).

This filter removes small background structures such as holes in the mask. The size of the affected structures is controlled by the shape and size of the kernel.

Inputs

Mask

A binary mask.

Type: Image4DBool, Required, Single

Outputs

Out

A binary mask with the same spatial properties as the input mask.

Type: Image4DBool

Settings

Kernel Selection

The shape of the structuring element.

Values: Annulus, Ball, Box, Cross

Radius X Integer

The radius of the kernel in the X direction, specified in voxels.

Radius Y Integer

The radius of the kernel in the Y direction, specified in voxels.

Radius Z Integer

The radius of the kernel in the Z direction, specified in voxels.

Safe Border Boolean

A safe border is added to input image to avoid borders effects. It is removed after the closing operation is done.
