DivideImage

Advanced

Module: FoundationLite

Divides each pixel by a scalar value.

Name Type Description
Input value
 inImage Image Input image
Input value
 inRoi Region* Range of pixels to be processed
Input value
 inValue Real Divisor
Output value
 outImage 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.
