ErodeRegion_AnyKernel


Header: AVL.h
Namespace: avl
Module: FoundationBasic

Performs a morphological erosion on a region using an arbitrary kernel.

Applications: Making the region thinner in a non-symmetrical way or removing small parts of a particular shape.

Syntax

C++
C#
 
void avl::ErodeRegion_AnyKernel
(
	const avl::Region& inRegion,
	const avl::Region& inKernel,
	atl::Optional<const avl::Location&> inKernelAnchor,
	avl::Region& outRegion
)

Parameters

Name Type Default Description
Input value inRegion const Region& Input region
Input value inKernel const Region& Kernel shape (any)
Input value inKernelAnchor Optional<const Location&> NIL Location within inKernel, defining its center
Output value outRegion Region& Output region

Description

The operation is a cousin of the ErodeRegion filter, yet it uses any proper region selected by user as a structuring element. The center of a kernel is assumed to be at location (width/2,height/2). Refer to the ErodeRegion article for further information regarding the morphological erosion itself.

Examples

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.

Errors

List of possible exceptions:

Error type Description
DomainError Empty kernel on input in ErodeRegion_AnyKernel.
