[Insight-users] What kind of C++ knowledge I need to know in order to use ITK?

[daniel mark]

Hello all:

I would like to start to learn ITK. However, I found the lots of C++
techniques used by ITK is strange to me.

For example:
itk::Functor::Acos< TInput, TOutput >

I know this is a kind of silly question, but I really need to get some helps.



Thank you
-Daniel
