Comments:
------------------------------------------------------------------------- ------------------------------------------------------------------------- This is a simple and useful form of Cost function, which should be used when the cost is derived from a pairwise Energy(i,j,a,b) The huge advantage is that only 1 virtual function is left to the user ------------------------------------------------------------------------- -------------------------------------------------------------------------

Methods:

SimplePairwiseCostC(TraceC t = TraceC(),int _nobjs = 0,int _nlabs = 0): Constructor
~SimplePairwiseCostC(): virtual destructor You must supply this function -----------------------------
double Energy(int i,int j,int a,int b): return the pairwise energy Thes functions are taken care of now for you --------------------------------------------
double Energy(const HardAssignC & r)
double Energy(const SoftAssignC & r): return the energy of the overall labelling It is assumed that this is slower and to be used sparingly MFTCostC stuff --------------
void GetMFTSupport(SoftAssignC & q,int i,const SoftAssignC & work): returns the support for one object
SoftAssignC GetMFTSupport(const SoftAssignC & work): returns the support GradAssCostC stuff ------------------
void GetGradAssSupport(SoftAssignC & q,int i,const SoftAssignC & work): returns the support for one object
SoftAssignC GetGradAssSupport(const SoftAssignC & work): returns the support SACostC stuff -------------
double GetEnergy(int i,int a,const HardAssignC & r): get the energy for object i with label a, or at least the part of the energy affected by changing labels on object i only
RealSArray1dC LoadEnergy(int i,const HardAssignC & r): Load up the array work with the energies for each label of object i given global assignment r
void TrapUndefinedVirtual(const char * fname): the crude but efective way to catch virtual functions that have not been overridden
double Energy(int i,int j,int a,int b): return the pairwise energy
double Energy(const HardAssignC & r): return the energy of the overall labelling It is assumed that this is slower and to be used sparingly
double Energy(const SoftAssignC & r): return the energy of the overall labelling It is assumed that this is slower and to be used sparingly Mean Field Theory -----------------
void GetMFTSupport(SoftAssignC & q,int i,const SoftAssignC & work): returns the support for one object
SoftAssignC GetMFTSupport(const SoftAssignC & work): returns the support Graduated assignment --------------------
void GetGradAssSupport(SoftAssignC & q,int i,const SoftAssignC & work): returns the support for one object
SoftAssignC GetGradAssSupport(const SoftAssignC & work): returns the support Simulated Annealing -------------------
double GetEnergy(int i,int a,const HardAssignC & r): get the energy for object i with label a, or at least the part of the energy affected by changing labels on object i only
RealSArray1dC LoadEnergy(int i,const HardAssignC & r): Load up the array work with the energies for each label of object i given global assignment r
