NegateImage

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

Syntax

C++
C#

void avl::NegateImage
(
const avl::Image& inImage,
atl::Optional<const avl::Region&> inRoi,
avl::Image& outImage
)

Parameters

Name Type Default Description
inImage const Image& Input image
inRoi Optional<const Region&> NIL Range of pixels to be processed
outImage 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:
• For the unsigned pixel types: (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.

In-place Processing

This function supports in-place data processing - you can pass the same reference to inImage and outImage

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.
