[Insight-users] Projection image filter ?

[Miller, James V (GE, Research)]

Gaetan, 

I suggest modifying the AccumulateImageFilter to have more modes of 
composition.  No reason to have an additional filter.

Yes, I want to project the image along one of the main axis, but the 
AccumulateImageFilter seems to be limited to the sum or the mean of all pixel 
on the axis, while I want the maximum intensity projection :-/
Some other statistics parameters may also be interesting, like minimum, mean, 
median, variance, ...

I think projection is a quite common operation in image analysis. Should I 
create a new filter ?
