Summary0002614: Label statistics should report center of mass

Just like the summary says. It would be great if Slicer could show me the center of mass of a structure somehow.

The label statistics module seems the logical place.

TagsNo tags attached.

I'm maybe we should make a list of metrics to add - center of mass is one that makes sense. I think ITK has some nice filters to characterize things and maybe with SimpleITK we would get a whole bunch with minimal coding.

Some ideas:

  • count of # of islands (blobs)
  • other moments
  • max/min dimensions across certain axes
  • aspect ratio

This is a new feature, which by the way is currently being developed for Segment Statistics module (by QIICR team).

@fedorov is center of mass planned for SegmentStatistics? I don't see that it's in the current version. Perhaps we should add a "Mass Properties" plugin (or similar) for calculations like this.

@pieper no, there are no plans in place to add this kind of plugin. I can see how it can be useful, but I just don't have cycles to work on this. Contributions are always welcomed - now that the plugins infrastructure is in place for Segment Statistics, this should hopefully be straightforward. It will be good to put it to work for this specific task.

Probably it is simpler to extend existing plugins to compute this new metric than create a new plugin, but both approaches should work.
