[Insight-users] Regarding arbitrary region extraction

[Luis Ibanez]

Hi Xuanaux,

You may find useful to look at the following filters:

http://www.itk.org/Doxygen/html/classitk_1_1PolylineMask2DImageFilter.html
http://www.itk.org/Doxygen/html/classitk_1_1PolylineMaskImageFilter.html

They can be used for masking an image by using
a polyline.


     Regards,


             Luis
