# ITK Binary Morphological Closing Image Filter

binary morphological closing of an image.

## Group (Subgroup)

ITKBinaryMathematicalMorphology (BinaryMathematicalMorphology)

## Description

This filter removes small (i.e., smaller than the structuring element) holes and tube like structures in the interior or at the boundaries of the image. The morphological closing of an image "f" is defined as: Closing(f) = Erosion(Dilation(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.

This code was contributed in the Insight Journal paper: "Binary morphological closing and opening image filters" by Lehmann G. <https://www.insight-journal.org/browse/publication/58>

### 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. |
| Foreground Value | Scalar Value |Float64 | Set the value in the image to consider as 'foreground'. Defaults to maximum value of InputPixelType. |
| Safe Border | Bool |  | A safe border is added to input image to avoid borders effects and remove it once the closing is done |

### Input Cell Data

| Parameter Name | Parameter Type | Parameter Notes | Description |
|----------------|----------------|-----------------|-------------|
| Image Geometry | Geometry Selection | Image | Select the Image Geometry Group from the DataStructure. |
| Input Cell Data | Array Selection | Allowed Types: int8, uint8, int16, uint16, int32, uint32, int64, uint64 | The image data that will be processed by this filter. |

### Output Cell Data

| Parameter Name | Parameter Type | Parameter Notes | Description |
|----------------|----------------|-----------------|-------------|
| Output Cell Data | DataObjectName |  | The result of the processing will be stored in this Data Array inside the same group as the input data. |
