Module: | FoundationBasic |
Performs a morphological black top hat (bottom hat) operation on a region using a predefined kernel.
Syntax
C++
C#
void avl::BottomHatRegion ( const avl::Region& inRegion, avl::KernelShape::Type inKernel, int inRadiusX, atl::Optional<int> inRadiusY, avl::Region& outRegion )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inRegion | const Region& | Input region | |||
inKernel | KernelShape::Type | Kernel shape (predefined) | |||
inRadiusX | int | 0 - | 1 | Nearly half of the kernel's width (2*R+1) | |
inRadiusY | Optional<int> | 0 - | NIL | Nearly half of the kernel's height (2*R+1), or same as inRadiusX | |
outRegion | Region& | Output region |
Description
Extracts small parts which do not belong to region. Uses predefined kernels.
Is performed by running consecutively two filters. CloseRegion to remove small holes from region and RegionDifference to remove rest of the region.
