Detailed Description

template<class T>
class drain::FuzzyStep< T >

A simple linear transition from 0 to 1 .

Template Parameters

T	- input storage type
T2	- output storage type

Examples with and without physical scaling to (0.0,1.0), setting step at 50% intensity (128 and 0.5):

drainage image-gray.png        --iFuzzyStep 64:192    -o fuzzyStep.png
drainage image-gray.png -R 0:1 --iFuzzyStep 0.25:0.75  -o fuzzyStep-phys.png

When changing storage type, scaling must be given explicitly (here 256, from C to S ) or physically with -R :

drainage image-gray.png  -R 0:1 -T S --iFuzzyStep 0.25:0.5 -o fuzzyStep-16bit-phys.png

Fuzzy Step.
