[Insight-users] Modify a ball Structuring Element

[Gaëtan Lehmann]

Hi Irene,

You may be interested in the methods in the FlatStructuringElement  
made to transform an image to a structuring element, and a structuring  
element to an image.
That way, you can prepare easy a complex structuring element in an  
image, or check the structuring element shape visually.

You will find the FlatStructuringElement class in the article  
"Efficient implementation of kernel filtering" on the Insight Journal.

Regards,

Gaëtan
