void	alphaExpansion (drwnSegImageInstance *instance, double contrastStrength=0.0, double higherOrderStrength=0.0, double longRangeStrength=0.0) const
	Alpha-expansion inference given instance unary terms, pairwise strength and higher-order strength (modifies `instance`). When constructing graphs the S set (nomially 1) takes value and the T set (nominally 0) takes each variable's previous value.

double	energy (const drwnSegImageInstance *instance, double contrastStrength=0.0, double higherOrderStrength=0.0, double longRangeStrength=0.0) const
	Return the energy of a given instance labeling.

Protected Member Functions
virtual void	addAuxiliaryVariables (drwnMaxFlow g, const drwnSegImageInstance instance) const
	adds node to the graph for any auxiliary variables (e.g., as required for higher-order terms)

double	addUnaryTerms (drwnMaxFlow g, const drwnSegImageInstance instance, int alpha, int varOffset=0) const
	add unary potentials to max-flow graph for a given alpha-expansion move and return constant energy component

double	addPairwiseContrastTerms (drwnMaxFlow g, double contrastStrength, const drwnSegImageInstance instance, int alpha, int varOffset=0) const
	add pairwise contrast potentials to max-flow graph for a given alpha-expansion move and return constant energy component

double	addLongRangePairwiseTerms (drwnMaxFlow g, double longRangeStrength, const drwnSegImageInstance instance, int alpha, int varOffset=0) const
	add long-range pairwise potentials to max-flow graph for a given alpha-expansion move and return constant energy component

virtual double	addHigherOrderTerms (drwnMaxFlow g, double higherOrderStrength, const drwnSegImageInstance instance, int alpha, int varOffset=0) const
	add higher-order potentials to max-flow graph for a given alpha-expansion move and return constant energy component

double	computeUnaryEnergy (const drwnSegImageInstance *instance) const
	compute energy contribution from unary potentials

double	computePairwiseContrastEnergy (const drwnSegImageInstance *instance, double contrastStrength) const
	compute energy contribution from pairwise contrast potentials

double	computeLongRangePairwiseEnergy (const drwnSegImageInstance *instance, double longRangeStrength) const
