Module: Erosion / Ball Erosion ()

Description:

Ball Erosion is one of the configurations of the module Erosion. For other configurations, see the port Type.

For an introduction, see:

• section Morphology
• introduction and definition for erosions

This module performs a 3D erosion of an image using a structuring element matching with a sphere.

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

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 Erosion,
• Disk Erosion,
• Line Erosion,
• Ball Erosion,
• Color Erosion.

Interpretation

This port specifies whether the input will be interpreted as a 3D volume or a stack of 2D images for processing. The port is grayed if alternate interpretation is not available.

Size

This port refers to the half-kernel size.

Precision

This port refers to the precision mode used (Precise or Faster).
