Creates a monochromatic image by summing the values of the input image channels with saturation.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
public static void AddChannels_Saturation ( AvlNet.Image inImage, NullableRef<AvlNet.Region> inRoi, AvlNet.Image outImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.NullableRef<AvlNet.Region> | Range of pixels to be processed. Default value: atl::NIL. | |||
outImage | AvlNet.Image | output mono image. |
Description
This operation sums with saturation values of the given inImage image channels to obtain a monochromatic image.
Firstly, the filter performs ordinary addition of pixel values from each channel. Then, comparison with maximal allowable value for single channel is performed. Such value depends on the pixel type - for example, if the pixel type is UInt8, maximal allowable value for each single channel is 255. The result of addition with saturation is chosen as a minimal value of computed sum and allowable maximum - for example, if the input image has three R, G, B channels and pixel type of UInt8, the result of addition with saturation is chosen as min(R + G + B, 255).
