AVL.NormalizeLocalBrightness_Mean

Normalizes local brightness of the image. Internally uses Mean smoothing.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void NormalizeLocalBrightness_Mean
(
	AvlNet.Image inImage,
	NullableRef<AvlNet.Region> inRoi,
	int inRadiusX,
	int? inRadiusY,
	float inTargetMean,
	float inGammaValue,
	AvlNet.Image outImage
)

Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inRoiAvlNet.NullableRef<AvlNet.Region>Range of pixels to be processed. Default value: atl::NIL.
inRadiusXint<0, INF>10Nearly half of the kernel's width (2*R+1). Default value: 10.
inRadiusYint?<0, INF>Nearly half of the kernel's height (2*R+1), or same as inRadiusX. Default value: atl::NIL.
inTargetMeanfloat128.0fTarget mean brightness. Default value: 128.0f.
inGammaValuefloat<0.01f, 8.0f>1.0fGamma coefficient, where 1.0 is neutral. Default value: 1.0f.
outImageAvlNet.ImageOutput image.

Description

This filter normalizes every pixels brightness to inTargetMean based on a local average calculated using SmoothImage_Mean passing to it parameters inRadiusX and inRadiusY.

Gamma correction can be performed on the image before normalization through the inGammaValue parameter.
