[Insight-users] units of SetNoiseLevel in itkGradientVectorFlowImageFilter

[Amardeep Singh]

Dear ITK Users

I am currently working with the "itkGradientVectorFlowImageFilter" and I 
stumbled across the
"SetNoiseLevel" function. Can anyone tell me the units of the noise 
level that is supposed to be set?
 From the constructor of the filter, I see that a standard value seems 
to be 200. I do not know the noise level of my
images. So is 200 a reasonable value? Can I estimate the noise of my 
images somehow in ITK?
Thank you very much for any advice.

Best regards
Amar
