[Insight-developers] Re: [Insight-users] concept checking in AccumulateImageFilter

[Gaetan Lehmann]

Hi,

The check is correct. The output is an image of the same dimension to keep the 
info of the output image on the same dimension (the docstring is surely a lot 
more clear than me).
I don't think it will work if you try to build it with a dim=3 in input and 
dim=2 in output.
It would be nice to be able to set the dim=3 or dim=2 in output, but the code 
will surely be difficult to write.
