Computes the sigmoid function pixel-wise.
A linear transformation is applied first on the argument of the sigmoid function. The resulting total transform 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.
