[ITK-users] Numeric traits

[Abdul Abdul]

Hello,

I came across the following statement:

PixelType label = itk::NumericTraits<PixelType>::One;

It seems to be related to numric traits, which I have visited its
documentation website, here
<http://www.itk.org/Doxygen/html/classitk_1_1NumericTraits.html>, but, yet,
didn't get the idea of the statement.

Can you kindly just describe to me what the statement means?

Thanks.
