Namespace: | fil |
Module: | FoundationLite |
Creates a monochromatic image by averaging the input image channels.
Syntax
void fil::AverageChannels ( const fil::Image& inImage, ftl::Optional<const fil::Region&> inRoi, fil::Image& outImage )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
![]() |
inImage | const Image& | Input image | |
![]() |
inRoi | Optional<const Region&> | NIL | Range of pixels to be processed |
![]() |
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.
