void avl::TopHatRegion ( 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 from region small parts. Uses predefined kernels.
Is performed by running consecutively two filters. OpenRegion to remove small parts from region and RegionDifference to remove rest of the region.
