AVL.CorrectGamma(AvlNet.ImagePointTransformsState, AvlNet.Image, AvlNet.Region, float, AvlNet.Image)

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax


public static void CorrectGamma(
	ref AvlNet.ImagePointTransformsState ioState,
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inValue,
	out AvlNet.Image outImage
)

Parameters

ioState: Type: AvlNet.ImagePointTransformsState
inImage: Type: AvlNet.Image
inRoi: Type: AvlNet.Region
inValue: Type: System.Single
outImage: Type: AvlNet.Image

Description

The gamma correction is a standard nonlinear transformation of pixel brightness that was developed as a tool for the compensation of CRT display input-output characteristic. The operation scales brightness of each inImage pixel to the 0.0 - 1.0 range, exponentiates it to the power of inValue, and then scales the result back to the pixel values range.

Examples

The CorrectGamma performed on the sample image with inValue = 2.0 (left image) and inValue = 0.5 (right image).

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.
