Hi everyone,

In ITK manual, 
sigmoid filter example has 0-255 range & alpha, beta values are taken as per actual intensity of pixels in ROI

but when we go to level set segmentation, Sigmoid values are between 0-1 (speed image)
is there any requirement of normalization etc ?
can any1 help me to clarify this doubt?

thank you
