Performs a morphological closing on a region using selected predefined kernel.
|inKernel||KernelShape||Kernel shape (predefined)|
|inRadiusX||Integer||0 -||Nearly half of the kernel's width (2*R+1)|
|inRadiusY||Integer*||0 -||Nearly half of the kernel's height (2*R+1), or same as inRadiusX|
The operation performs a morphological closing, which is a tool used for filling gaps in a region. The operation is a convolution of two basic morphological operations:
- Firstly, the input region is dilated using DilateRegion operation.
- Then, the resulting region is eroded using ErodeRegion operation.
During the dilation gaps that are small enough are actually closed, while further erosion assures that the width of region limbs is preserved.
Both of the component operations are conducted using the same inKernel, inRadiusX and inRadiusY parameters.
- Increase inRadiusX to fill-in bigger gaps in the region.
- Change inKernel to Ellipse to make the filter work equally strongly in each direction (execution will be slower).
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
|DomainError||Unsupported kernel in CloseRegion.|
