[Insight-users] Filling holes

Thu Oct 7 04:40:57 EDT 2010

Hi,

Filling closed structures, independently of their size, is what  
GrayscaleFillholeImageFilter does.
It works on binary images as well if the objects have a higher value  
than the background.

There is also a more efficient binary version, but it's not yet  
integrated in ITK. You can download it from

binaryAttributeMorphology/

Regards,

Gaëtan
