[Insight-developers] LabelMaps and the Perimeter Estimation

[Bradley Lowekamp]

Gaetan,

Have you seen the following bug:
http://www.itk.org/Bug/view.php?id=11934

I encountered this bug myself. It is quite serious because the roundness attribute can become quite erroneous, as I have seen it >2.0 when theoretically it should always be less then 1.0. The miscalculation is causing me to have some trust issues with using this code and relaying on the computed attributes.

In this current state I would not recommend moving the LabelMaps out of ITK review.

Your IJ paper says "More details about perimeter estimation will be published in another article". I only bring up the issue because LabelMaps are quite useful, and would like they to quickly be placed in the reliable category. 

Thanks,
Brad
