[Insight-users] itkGaussianSpatialObject question

[Dr. Uwe Köhler]

HiYa,

I played around with the itkGaussianSpatialObject and noticed that the radius 
is only used to calculate the bounding box. It is not used to broaden the 
gaussian. I can perfectly adjust the width of the gaussian by the scale of 
the transformation. I fear I do get the wrong bouding box and I do believe 
the radius is not required. Btw, how big should the bounding box be? The 
gaussian only drops to zero at infinity. What is a good cut-off? Adjusting 
that by just one radius is difficult for gaussians that are scaled 
unisotrope.

Any suggestions?

Uwe
