ImageDev

DilationBall3d

Performs a three-dimensional erosion using a structuring element matching with a sphere.

Access to parameter description

For an introduction: This command supports two modes: a fast mode that approximates a spherical structuring element by combining dilations using 6, 18 and 26 neighborhoods, and a precise mode (slower) that ensures a real spherical structuring element. The mode can be selected with the precision parameter.

Class Syntax

Parameters

Class Name DilationBall3d

Parameter Name Description Type Supported Values Default Value
input
inputImage
The input image. The image type can be integer or float. Image Binary, Label, Grayscale or Multispectral nullptr
input
kernelRadius
The length of the sphere radius in voxels. UInt32 >=1 3
input
precision
The precision of the computation method.
FASTER The operation is computed with the fast mode, which approximates a circular structuring element by combining erosions using 6, 18 and 26 neighborhoods.
PRECISE The operation is computed with the precise mode (slower), which ensures a real spherical structuring element.
Enumeration FASTER
output
outputImage
The output image. Its dimensions and type are forced to the same values as the input image. Image nullptr
