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.
