Module: Dilation / Cube Dilation ()

Description:

Cube Dilation is one of the configurations of the module Dilation. For other configurations, see the port Type.

For an introduction, see:

• section Morphology
• introduction and definition for dilations

This module uses the default structuring element of 8 pixels for a square grid.

With a 3D image, this module uses the default structuring element of 6, 18 or 26 voxels.

Figure 2: Structuring elements: 6 voxels, 18 voxels and 26 voxels.

Connections:

Input Image [required]
The input image to be processed. Supported types include: binary and label image (Uniform Label Field), grayscale image (Uniform Scalar Field) and color image (Uniform Color Field).

Ports:

Type

This port selects the configuration of this module. The available configurations are:

• Cube Dilation,
• Disk Dilation,
• Line Dilation,
• Ball Dilation,
• Color Dilation.

Interpretation

This port specifies whether the input will be interpreted as a 3D volume or a stack of 2D images for processing.

• "3D": the module configuration is set to 3D. The image will be processed as a whole in 3D.
• "XY planes": the module configuration is set to 2D. The image will be processed slice per slice.

Neighborhood

In 3D configuration, this port refers to the type of connectivity considered for processing adjacent voxels:

• 6: voxels with a common face are considered connected
• 18: voxels with at least one common edge are considered connected
• 26: voxels with at least one common vertex are considered connected

Size

This port refers to the half-kernel size.
