[Insight-developers] min. max over ROI (floodfilliterator)

[Stephen R. Aylward]

Hi,

Should the itk "thing" to calculate a min, max, etc of an image for an 
ROI (done internally using the floodfilliterator) be implemented as a 
filter or an image calculator?

As a filter, it doesn't produce an image as an output.

An image calculator seems appropriate, but it will cause a recalc on 
every call since they don't (by default) keep track of whether or not 
the input has changed (could be done, however, by having the calculator 
monitor the input image's modified time - Julien's suggestion).

We have image min, max, etc implemented both ways in itk at this time.

Will do as an image calculator unless I (Julien) hear otherwise.

Thanks,
Stephen
