[Insight-developers] memory usage

[Bill Lorensen]

Leila,

You can try a couple of thing:

If you are running through parts of your pipeline in one pass, use
ReleaseDataFlagOn() on those filters.

If you are running pixel wise operations, use InPlaceOn().

There is an itkMemoryProbe class that might help monitoring usage.
I've never used it, but there is an illustrative test.

Regards,

Bill
