[ITK-users] Problem calculating surface ITK mesh

[Dženan Zukić]

Hi Elisabeth,

you could try using BinaryImageToStatisticsLabelMapFilter
<https://itk.org/Doxygen/html/classitk_1_1BinaryImageToStatisticsLabelMapFilter.html>
or some other filter from the same group
<https://itk.org/Doxygen/html/group__ITKLabelMap.html>. The feature you
want to pay attention to is 'perimeter'.

Regards,
Dženan
