AverageChannels


Header: AVL.h
Namespace: avl

Creates a monochromatic image by averaging the input image channels.

Syntax

void avl::AverageChannels
(
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	avl::Image& outImage
)

Parameters

Name Type Default Description
Input value
 inImage const Image& Input image
Input value
 inRoi Optional<const Region&> NIL Range of pixels to be processed
Output value
 outImage Image& Output image

Description

The operation computes the monochromatic average of inImage color channels. Average being computed at each pixel is a standard arithmetic mean.

Examples

AverageChannels run on example image.
