#include <itkExponentialLimiterFunction.h>

Detailed Description

template<class TInput, unsigned int NDimension>
class itk::ExponentialLimiterFunction< TInput, NDimension >

A soft limiter.

If the input value exceeds the upper/lower threshold the output is diminished/increased, such that it never will exceed the UpperBound/LowerBound. It does this in a smooth manner, with an exponential function.

$L(f(x)) = (T-B) e^{(f-T)/(T-B)} + B,$

where $B$ is the upper/lower bound and $T$ the upper/lower threshold
