Module: Closing / Line Closing 3D ()

Description:

Line Closing 3D is one of the configurations of the module Closing. For other configurations, see the port Type and port Interpretation.

For an introduction, see:

• section Morphology
• introduction and definition for closing

This module performs a 3D closing using a linear structuring element. Closing direction is given by its Euler representation (, ).

Closing direction given as (, ) is computed as follows:

This direction can be illustrated on the unit sphere:

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 Closing,
• Disc Closing,
• Line Closing,
• Ball Closing,
• Minimal Linear Closing,
• Color Closing.

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.

Theta Angle

This port refers to the value of the angle in degrees.

Phi Angle

This port refers to the value of the angle in degrees.

Size

This port refers to the half-kernel size.
