Performs a morphological opening on a region using a 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 opening, which is a tool used for removing thin parts from a region. The operation is a convolution of two basic morphological operations:
- Firstly, the input region is eroded using ErodeRegion operation.
- Then, the resulting region is dilated using DilateRegion operation.
During the erosion thin parts of a region are eliminated, while further dilation 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 remove more small parts from 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 OpenRegion.|
