[Insight-users] NeighborhoodOperator

[l franz]

Hi everybody,

I want to create a neighborhood operator which inherits of 
"NeighborhoodOperator" class. My operator will weight each pixels of a 
NDimensional neighborhood through a kind of inner product (the output of 
this inner product will be a neighborhood with weighted pixels). So my 
operator performs on all the neighborhood (and not in a particular 
direction) and its size is equal to the neighborhood size.

So, my operator is not directional. In this case and if I understand well 
the documentation, I have to implement two methods:
1. GenerateScalarCoefficients
2. ScalarFill

So, I don't need to implement the "GenerateCoefficients" and "Fill" methods 
(for directional operators) like in GaussianOperator or in 
DerivativeOperator.

But, I don't know how to create the "GenerateScalarCoefficients" and 
"ScalarFill" methods. What do they have in input arguments? What do they 
return? Do they have to call a particular method inherited from 
NeighborhoodOperator??

I think that "GenerateScalarCoefficient" method is similar to 
"GenerateCoefficients" method. It takes no input argument and return a 
"CoefficientVector" with the desired coefficients. 
But I have no ideas of how to implement the "ScalarFill" method.

Does someone know about it? Or does anybody know where I can find an exemple 
of an non-directional neighborhood operator??

Thanks,
Cheers,

Franz
