CorrectGamma
Performs gamma correction.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inImage | Image | Input image | |
|
inRoi | Region* | Range of pixels to be processed | |
|
inValue | Real | 0.01 - 8.0 | Gamma coefficient, where 1.0 is neutral |
 |
outImage | Image | Output image | |
Only the following inImage pixel formats are supported: int8, uint8, int16, uint16, int32
Applications
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.

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.
