[Insight-developers] TComputation type removed from filters

[Luis Ibanez]

Hi,

As we discussed at the UNC meeing,
the "TComputation" template parameter that was used in some
filters has been removed.

It is replaced in general by the following type "RealType":

typedef typename TInputImage::PixelType InputPixelType;
typedef typename NumericTraits<InputPixelType>::RealType RealType;


In the case of the GradientToMagnitudFilter, the pixel type of
the input is  Vector<> so an additional type is required to get the
component type:

typedef typename TInputImage::PixelType InputPixelType;
typedef typename InputPixelType::ValueType InputValueType;
typedef typename NumericTraits<InputValueType>::RealType RealType;


Also the Output type of these filters has now a default type for
the template parameters.   The same rest to be done for the
other filters.
