[Insight-users] itk::StatisticsLabelMapFilter with input image size != feature image size

[Gelas, Arnaud Joel Florent]

Vince,

Thanks for your reply!

That's also what I thought; but I got some code from a student with such a case. The code does not fail, and even provides results (most probably not the right ones, but it does).

Would it be possible to add exceptions to handle these cases (different origin, spacing, etc...) if it is not supposed to work ?

Thanks,
Arnaud

Arnaud,

My reading of the algorithm is that the images must be of the same size, spacing, directions, and origin to work correctly.

Hi Gaetan,

In itk::StatisticsLabelMapFilter, does the feature image need to be
aligned (same origin, same spacing) with the input one?

For instance, can you use this filter with a feature image larger than
the input one, i.e. the input one is a ROI from one label map with same
spacing, origin from the feature image?

Thanks,
Arnaud
