[Insight-users] Sigmoid Filter

[Maria Cira Avvinto]

Thank you Daniel;
my problem is experimentation. I have red section in
ITK manual, but i don't understood the wheight of this parameters in
the filter; for example: if i choose a big  Alpha (or Beta) value how
change the output? Is there a range of specific value? What's the
better choise? How can i find the priori knowledge of my image? How
can i maximize my signal to noise ratio? Tnx.
