Image Point Transforms

Select a function from the list below.

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