[Insight-developers] efficient way to avoid the outside pixel ?

[Gaetan Lehmann]

Hi,

I already asked the question, but didn't get an answer.
Is there an efficient (and elegant) way to avoid getting the pixels  
outside the image in a neighborhood iterator ? Most of the time, it is  
possible to use a constant boundary value, but it's not really nice, and  
not really efficient.

Thanks,

Gaetan
