AVL.DivideImage(AvlNet.Image, AvlNet.Region, float, AvlNet.Image)

Divides each pixel by a scalar value.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


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

Parameters

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

Description

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.

Examples

DivideImage performed on the sample image with inValue = 2.0.

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.

Errors
