AVL.DivideImage Method

Divides each pixel by a scalar value.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

public static void DivideImage(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inValue,
	out AvlNet.Image outImage
)

Name	Type	Default	Description
inImage	AvlNet.Image		Input image.
inRoi	AvlNet.Region		Range of pixels to be processed. Default value: atl::NIL, or null.
inValue	float	2.0f	Divisor. Default value: 2.0f.
outImage	AvlNet.Image		Output image.

The operation decreases the brightness of the inImage dividing each of its pixels by a fixed value.

$\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = \frac{\text{\textbf{InImage} }_{i,j} }{\text{\textbf{inValue} } }$

Whenever the resulting value exceeds the range of pixel values, it is clipped to the nearest proper value.

DivideImage performed on the sample image with inValue = 2.0.

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.
