AVL.NegateImage(AvlNet.Image, AvlNet.Region, AvlNet.Image)

Reverts the pixel value range (unsigned) or applies numeric negation (signed).

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax


public static void NegateImage(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	out AvlNet.Image outImage
)

Parameters

inImage: Type: AvlNet.Image
Input image
inRoi: Type: AvlNet.Region
Range of pixels to be processed, or null.
outImage: Type: AvlNet.Image
Output image

Description

The operation negates the pixel values of the inImage. Depending on the pixel type, the negation is defines as follows:

For the signed pixel types: $\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = -\text{\textbf{InImage} }_{i,j}$
For the unsigned pixel types: $\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = \text{\textbf{MaximalValue} } - \text{\textbf{InImage} }_{i,j}$ (which can be thought of as mirroring the pixel values around the center of the pixel values range)

Examples

The NegateImage performed on the sample image.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT8, SINT16, REAL.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.
