AVL.AddChannels

Creates a monochromatic image by summing the values of the input image channels.

Namespace: AvlNet AVL.NET.dll

Syntax

C++
C#

public static void AddChannels
(
AvlNet.Image inImage,
NullableRef<AvlNet.Region> inRoi,
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.
outImageAvlNet.Imageoutput mono image.

Description

This operation sums values of the given inImage image channels to obtain a monochromatic image.

Examples

 Image with one channel on the input of the filter (on the left) doesn't affect the image - see the image on the right. Input RGB image (on the left) converted to single-channel image (on the right) with pixel values obtained from summing values of input image channels. For example, if a pixel from input image in each R, G and B channel has values {255, 0, 0}, corresponding pixel in the output image will have value {255} (because 255 + 0 + 0 = 255).

Hardware Acceleration

This operation is optimized for AVX2 technology for pixels of types: 2xUINT8, 3xUINT8, 4xUINT8, 2xUINT16, 3xUINT16, 4xUINT16.

This operation is optimized for SSSE3 technology for pixels of types: 2xUINT8, 3xUINT8, 4xUINT8, 2xUINT16, 3xUINT16, 4xUINT16.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.
