AVL.ErodeImage Method

Replaces each pixel with the minimum of pixels within a kernel.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax

public static void ErodeImage(
	AvlNet.Image inImage,
	AvlNet.KernelShape inKernel,
	int inRadiusX,
	out AvlNet.Image outImage,
	out AvlNet.Region diagKernel
)

Parameters

Name	Type	Range	Default	Description
inImage	AvlNet.Image			Input image.
inKernel	AvlNet.KernelShape			Kernel shape.
inRadiusX	int	<0, INF>	1	Nearly half of the kernel's width (2*R+1). Default value: 1.
outImage	AvlNet.Image			Output image.
diagKernel	AvlNet.Region			Kernel shape.

Description

The operation replaces each pixel with the darkest pixel in its neighbourhood, thus shrinking bright areas in inImage and expanding the dark ones.

Examples

ErodeImage performed on the sample image with inKernel = Box, inRadiusX = 1, inRadiusY = 1.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: all formats (when inSourceRoi = NIL and inBorderColor = NIL).

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.

Errors

Error type	Description
DomainError	inBorderColor is relevant only when inSourceRoi is set to Auto (NIL) in ErodeImage.
DomainError	Not supported kernel on input in ErodeImage.
