9.12. ITK Binary Opening By Reconstruction Image Filter

binary morphological closing of an image.

Group (Subgroup)

ITKBinaryMathematicalMorphology (BinaryMathematicalMorphology)

Description

This filter removes small (i.e., smaller than the structuring element) objects in the image. It is defined as: Opening(f) = ReconstructionByDilatation(Erosion(f)).

The structuring element is assumed to be composed of binary values (zero or one). Only elements of the structuring element having values > 0 are candidates for affecting the center pixel.

Description

Kernel Radius

Vector of UInt32 Values

Order=X,Y,Z

The radius of the kernel structuring element.

Kernel Type

Choices

Set the kernel or structuring element used for the morphology.

Foreground Value

Scalar Value

Float64

Set the value in the image to consider as ‘foreground’. Defaults to maximum value of PixelType.

Background Value

Scalar Value

Float64

Set the value in eroded part of the image. Defaults to zero

Fully Connected

Bool

Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn.
