Class TonemapMantiuk

This algorithm transforms image to contrast using gradients on all levels of gaussian pyramid, transforms contrast values to HVS response and scales the response. After this the image is reconstructed from new contrast values.

Properties

Saturation

Gets or sets positive saturation enhancement value. 1.0 preserves saturation, values greater than 1 increase saturation and values less than 1 decrease it.

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

Scale

Gets or sets contrast scale factor. HVS response is multiplied by this parameter, thus compressing dynamic range. Values from 0.6 to 0.9 produce best results.

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

Create(Single, Single, Single)

Creates TonemapMantiuk object

Declaration
public static TonemapMantiuk Create(float gamma = 1F, float scale = 0.7F, float saturation = 1F)
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 scale

contrast scale factor. HVS response is multiplied by this parameter, thus compressing dynamic range. Values from 0.6 to 0.9 produce best results.
System.Single saturation
