Class TonemapReinhard

This is a global tonemapping operator that models human visual system.

Mapping function is controlled by adaptation parameter, that is computed using light adaptation and color adaptation. For more information see @cite RD05.

ColorAdaptation

Gets or sets chromatic adaptation in [0, 1] range. If 1 channels are treated independently, if 0 adaptation level is the same for each channel.

Declaration
public float ColorAdaptation { get; set; }
Property Value

System.Single

Intensity

Gets or sets result intensity in [-8, 8] range. Greater intensity produces brighter results.

Declaration
public float Intensity { get; set; }

System.Single

LightAdaptation

Gets or sets light adaptation in [0, 1] range. If 1 adaptation is based only on pixel value, if 0 it's global, otherwise it's a weighted mean of this two cases.

Declaration
public float LightAdaptation { get; set; }
Property Value
Type Description
System.Single

Methods

Create(Single, Single, Single, Single)

Creates TonemapReinhard object

Declaration
public static TonemapReinhard Create(float gamma = 1F, float intensity = 0F, float lightAdapt = 1F, float colorAdapt = 0F)
Parameters
Type Name Description
System.Single gamma

positive value for gamma correction. Gamma value of 1.0 implies no correction, gamma equal to 2.2f is suitable for most displays. Generally gamma > 1 brightens the image and gamma < 1 darkens it.
System.Single intensity

result intensity in [-8, 8] range. Greater intensity produces brighter results.
System.Single lightAdapt

light adaptation in [0, 1] range. If 1 adaptation is based only on pixel value, if 0 it's global, otherwise it's a weighted mean of this two cases.
System.Single colorAdapt

chromatic adaptation in [0, 1] range. If 1 channels are treated independently, if 0 adaptation level is the same for each channel.
