Module: Closing / Minimal Linear Closing ()

Description:

Minimal Linear Closing is one of the configurations of the module Closing. For other configurations, see the port Type.

For an introduction, see:

• section Morphology
• introduction and definition for closing

This module performs the intersection of the closings in several directions (binary case) or the minimum of the closings (grayscale case). This module is very useful when you work with circular shapes because it fills the holes in all directions. Like a classical closing transform, using this module with an appropriate threshold allows getting a Top Hat well adapted to the circular objects detection.

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.

Size

This port refers to the half-kernel size.

Number Of Angles

This port refers to the number of samples used around unit circle (or unit sphere in 3D).
