Module: Dilation / Disc Dilation ()

Description:

Disc Dilation is one of the configurations of the module Dilation. For other configurations, see the port Type and port Interpretation.

For an introduction, see:

• section Morphology
• introduction and definition for dilations

This module performs a 2D dilation of an image using a structuring element matching with a disc.

This module supports two modes: a fast mode which combines erosions using different neighborhoods and a precise mode (slower) which ensures a real disc structuring element.

See also: Disc Erosion.

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.

Size

This port refers to the half-kernel size.
