[ITK Community] sum of two objects ITK

[Luis Ibanez]

Hi Hana,

Are you referring to the parameter array type used in the image
registration framework ?

If so, nope, the parameters type doesn't provide an addition operator.

This is by design, because the parameters are not necessarily elements of a
vector space.


Consider for example, the case of the Versors (Unit Quaternions), where the
addition of
elements is not equivalent to the addition (or composition) of two
Quaternions.  The same
will apply to the Affine matrices (the addition of elements is not
equivalent to the composition
of two matrices).


  Hope this helps,


      Thanks


           Luis
