[Insight-users] ShiftScaleImageFilter problem

[Stefano Diciotti]

Hi,
I have found a difference between the documentation and the coding 
regarding the ShiftScaleImageFilter class:

On line 95 of "Insight/Code/BasicFilters/itkShiftScaleImageFilter.txx" 
we have:

value = (static_cast<RealType>(it.Get()) + m_Shift) * m_Scale;

Instead in the "Itk Software Guide", on page 121, the formula used is:
outputPixel = inputPixel * Scale + Shift

Personally, I think that the formulation given in the documentation is 
more correct, however it is important to match the two formulas.

Many thanks,

Stefano
