Detailed Description

template<class TInputImage, class TOutputImage>
class itk::SigmoidImageFilter< TInputImage, TOutputImage >

Computes the sigmoid function pixel-wise.

A linear transformation is applied first on the argument of the sigmoid fuction. The resulting total transfrom is given by

\[ f(x) = (Max-Min) \cdot \frac{1}{\left(1+e^{- \frac{ x - \beta }{\alpha}}\right)} + Min \]

Every output pixel is equal to f(x). Where x is the intensity of the homologous input pixel, and alpha and beta are user-provided constants.

virtual::itk::LightObject::Pointer itk::SigmoidImageFilter< TInputImage, TOutputImage >::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.
