Detailed Description

template<typename TInputImage, typename TFeatureImage, typename TSingleData>
class itk::RegionBasedLevelSetFunctionSharedData< TInputImage, TFeatureImage, TSingleData >

Helper class used to share data in the ScalarChanAndVeseLevelSetFunction.

This class holds cache data used during the computation of the LevelSet updates.

Based on the paper [22].

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
