SubtractFromImage

Module:	FoundationLite

Subtracts a scalar value from each pixel.

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

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

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

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

The SubtractFromImage performed on the sample image with inValue = 50.0.

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.
