Detailed Description

template<typename TInput = float, typename TOutput = double>
class itk::HeavisideStepFunction< TInput, TOutput >

Implementation of the classical Heaviside step function.

The Heaviside Step function is a piece-wise function:

virtual::itk::LightObject::Pointer itk::HeavisideStepFunction< TInput, TOutput >::CreateAnother ( void  ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<typename TInput = float, typename TOutput = double>
OutputType itk::HeavisideStepFunction< TInput, TOutput >::Evaluate ( const InputType input) const
virtual

Evaluate at the specified input position

Implements itk::HeavisideStepFunctionBase< TInput, TOutput >.

template<typename TInput = float, typename TOutput = double>
OutputType itk::HeavisideStepFunction< TInput, TOutput >::EvaluateDerivative ( const InputType input) const
virtual

Evaluate the derivative at the specified input position

Implements itk::HeavisideStepFunctionBase< TInput, TOutput >.
