|
||
|
|
* @brief Will perform opening or closing.
|
||
|
|
*
|
||
|
|
* vtkImageOpenClose3D performs opening or closing by having two
|
||
|
|
* vtkImageErodeDilates in series. The size of operation
|
||
|
|
* is determined by the method SetKernelSize, and the operator is an ellipse.
|
||
|
|
* OpenValue and CloseValue determine how the filter behaves. For binary
|
||
|
|
* images Opening and closing behaves as expected.
|
||
|
|
* Close value is first dilated, and then eroded.
|
||
|
|
* Open value is first eroded, and then dilated.
|
||
|
|
* Degenerate two dimensional opening/closing can be achieved by setting the
|
||
|
|
* one axis the 3D KernelSize to 1.
|
||
|
|
* Values other than open value and close value are not touched.
|
||
|
|
* This enables the filter to processes segmented images containing more than
|
||
|
|
* two tags.
