MultiplyImage


Module: FoundationLite

Multiplies 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 Multiplier
Output value outImage Image Output image

Description

The operation increases the brightness of an image by multiplying each of its pixels by a fixed value.

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

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

Examples

The MultiplyImage 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 Region exceeds an input image in MultiplyImage.

Complexity Level

This filter is available on Advanced Complexity Level.
