ClosingBallByReconstruction3d

Performs a three-dimensional closing by reconstruction with a structuring element matching with a cube.

Access to parameter description

A closing by reconstruction consists in applying a dilation followed by a morphological reconstruction. In the binary case, closing by reconstruction can be used for filling small holes without modifying edges of the large ones. In the grayscale case, opening by reconstruction can be used for performing a Top Hat by reconstruction for detecting dark small structures without getting artifacts from the boundary concavities of large structures.
Its 2D grayscale behavior is illustrated in the ClosingByReconstruction2d documentation (Figure 1).

Class Syntax

Parameters

Class Name ClosingBallByReconstruction3d

Parameter Name Description Type Supported Values Default Value
input
inputImage
The input image. Image Binary, Label or Grayscale 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
