Image Point Transforms

Select a function from the list below.

Name	Description / Applications	Modules
AbsoluteValueImage	Transforms pixel values to their absolute values pixel by pixel.	FoundationLite
AddNoiseToImage	Adds random noise to the image.	FoundationLite
AddToImage	Adds a scalar value to each pixel.	FoundationLite
ClipPixels	Sets pixels below the low value to the low value and above the high value to the high value.	FoundationLite
ColorizeImage	Shows a monochromatic image in false colors.	FoundationLite
CorrectGamma	Performs gamma correction. Image enhancement for human perception. For computer vision consider LogarithmImage.	FoundationLite
DivideImage	Divides each pixel by a scalar value.	FoundationLite
InvertImage	Applies numeric inversion (1/x) of the pixel values.	FoundationLite
LogarithmImage	Computes a natural logarithm of each pixel. Transforms an image in such a way that a quotient on the input image becomes a difference on the output image. This can be useful for dealing with variable illumination.	FoundationLite
LUTTransformImage	Changes pixel values for data stored in array.	FoundationLite
MultiplyImage	Multiplies each pixel by a scalar value.	FoundationLite
NegateImage	Reverts the pixel value range (unsigned) or applies numeric negation (signed).	FoundationLite
PowerImage	Exponentiates each pixel to the given power.	FoundationLite
ReplacePixels	Substitutes pixels having the specified value with a new value.	FoundationLite
ResaturateImage	Sets pixels below the low value to minimum, above the high value to maximum, and interpolates the rest.	FoundationLite
RescalePixels	Applies linear transformation to pixel values.	FoundationLite
RescalePixels_FixedRange	Transforms pixels value from given range into new one.	FoundationLite
SquareImage	Raises pixel values to the second power pixel by pixel.	FoundationLite
SquareRootImage	Transforms pixel values to their square roots pixel by pixel.	FoundationLite
SubtractFromImage	Subtracts a scalar value from each pixel.	FoundationLite
