Detailed Description

apply any (fixed) function to all pixels

The only parameter to be passed to the constructor must be a (monadic) function that takes a pixel value from the input image and produces a pixel value of the output image, i.e., its signature must be DataOut f(DataIn const&). A typical example is, e.g., log(), but any point operator (like e.g. thresholding) could be implemented through this more general monadic IP operator, notably shift or scale of intensity values.

Note that the input and output images are allowed to be identical.
