[Insight-users] structuring element for morphological operators

[Ehtiati, Tina (SCR US EXT)]

Hello,
 
I have questions related to the structuring elements used for
morphological operations such as dilation and erosion. 
I have been using the BallStructuringElement with the
itkGrayscaleErodeImageFilter and the itkGrayScaleDilateImageFilter. But
now I need to build
different kinds of structuring elements, for example cube of radius 12
and also 3D octagons. I would like to know how can I build a structuring
element of
my own design and use it along with the erosion and dilation filters. I
read the example on the NeighborhoodIterator (the example of sobel
filter), but still I cann't  figure out exactly what should I do? 
 
I would appreciate it if you could give me some hints!
 
Thanks
 
Tina
