[Insight-users] gamma parameter in VED by R. Manniesing et al.

[Oleksandr Dzyubak]

Dear Rashindra, Luis and ITK users,

I am trying to use VED (by R. Manniesing et al.) for denoising tubular 
like objects
and in particular I would like to suppress background over foreground.
 From the publication I found that it could be controlled through the 
Gamma parameter.
I tried to vary Gamma in a quite wide range and I did find any 
reasonable difference in the output images.

How can I increase the algorithms sensitivity to the gamma
or it is controlled by another parameter (or combination)? Which one?
Does gamma depend on the pixel size? In what manner if yes?

Thanks,

Alex
