MTBLengthEnergyKB2D2P4NNonPDE

@ALDParametrizedClass
public abstract class MTBLengthEnergyKB2D2PNonPDE
extends MTBLengthEnergyKBNonPDE

Implements the (standard) length energy using length approximation due to Kolmogorov/Boykov for two phases. Does NOT take invalid pixels into account This is an abstract class, neighborhood coordinates and weights have to be still defined. For notation see Danek, Matula: Graph cuts and approximation pf the Eucleidean metric on anisotropic grids, VISAPP 2010, 68-73.
