Detailed Description

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

Atan-based implementation of the Regularized (smoothed) Heaviside functions.

Author: Mosaliganti K., Smith B., Gelas A., Gouaillard A., Megason S.

This code was taken from the Insight Journal paper:

"Cell Tracking using Coupled Active Surfaces for Nuclei and Membranes"
https://doi.org/10.54294/wvwmf8

That is based on the papers:

"Level Set Segmentation: Active Contours without edge"
https://doi.org/10.54294/8jk6oy

and

"Level set segmentation using coupled active surfaces"
https://doi.org/10.54294/23ugmy
