#include <itkUnsharpMaskImageFilter.h>
Edge enhancement filter.
This filter subtracts a smoothed version of the image from the image to achieve the edge enhancing effect. https://en.wikipedia.org/w/index.php?title=Unsharp_masking&oldid=750486803#Photographic_unsharp_masking
It has configurable amount, radius (sigma) and threshold, and whether to clamp the resulting values to the range of output type.
Formula: sharpened=original+[itk::Math::abs(original-blurred)-threshold]*amount
If clamping is turned off (it is on by default), casting to output pixel format is done using C++ defaults, meaning that values are not clamped but rather wrap around e.g. 260 -> 4 (unsigned char).

UnsharpMaskImageFilter needs a larger input requested region than the output requested region (larger by the size of the Gaussian kernel). As such, UnsharpMaskImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

Verifies that the process object has been configured correctly, that all required inputs are set, and needed parameters are set appropriately. If not valid an exceptions will be thrown.
This method is called before UpdateOutputInformation() is propagated to the inputs.
The ProcessObject's implementation verifies that the m_NumberOfRequiredInputs are set and not null.
