java.lang.Objectde.unihalle.informatik.MiToBo.segmentation.levelset.core.DeltaApproxHelper
public class DeltaApproxHelper
Class calculating approximations to the Dirac impulse function.
The approximations used here are implemented according to
Chan and Vese, "An Active Contour Model without Edges", Scale-Space '99, LNCS 1682, pp. 141-151, Springer 1999.
Refer to DeltaApproxHelper.ApproxVersion
for details about the
available approximations.
