DivideImage


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.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Division by zero in DivideImage.
DomainError Region exceeds an input image in DivideImage.

Complexity Level
