[Insight-users] Re: One last call for help - neighborhood operator

[Ruben Schilling]

Hi Dave,

the question is how you define an image of arbitrary shape. In itk  
and all other software/theory I know of a 2D image is a rectangular  
matrix. You could fill the image with background values, but I don't  
know, if that is what you really want. When operating on arbitrary  
shaped neighborhoods it can be quite tricky to define good boundary  
conditions. Maybe you really want to stick to the neighborhood  
iterator and define operations voxel-wise to keep your arbitrary shape?

Best,
Ruben
