Hi all,<br><br>I just noticed that these two hierarchies seem to do the same thing - namely, accumulate/project a given image in a given direction, reducing the dimension in that direction to 1.<br><br>Correct me if I'm wrong, but doesn't itk::SumProjectionImageFilter do the same job as AccumulateImageFilter? Is there any reason that two separate hierarchies are maintained?<br>
