9.17. ITK Closing By Reconstruction Image Filter
Closing by reconstruction of an image.
Group (Subgroup)
ITKMathematicalMorphology (MathematicalMorphology)
Description
This filter is similar to the morphological closing, but contrary to the morphological closing, the closing by reconstruction preserves the shape of the components. The closing by reconstruction of an image “f” is defined as:
ClosingByReconstruction(f) = ErosionByReconstruction(f, Dilation(f)).
Closing by reconstruction not only preserves structures preserved by the dilation, but also levels raises the contrast of the darkest regions. If PreserveIntensities is on, a subsequent reconstruction by dilation using a marker image that is the original image for all unaffected pixels.
Closing by reconstruction is described in Chapter 6.3.9 of Pierre Soille’s book “Morphological Image Analysis: Principles and Applications”, Second Edition, Springer, 2003.
Input Parameter(s)
Parameter Name |
Parameter Type |
Parameter Notes |
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. |
|
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. |
|
PreserveIntensities |
Bool |
Set/Get whether the original intensities of the image retained for those pixels unaffected by the opening by reconstruction. If Off, the output pixel contrast will be reduced. |
