DistanceCoherence computes coherence between two points from the distance between them.
double getWeight()
get the weight of coherence.
void setWeight(double weight)
set the weight of coherence.
DistanceCoherence()
initialize the weight to 1.0.
double computeCoherence(PointInT &source, PointInT &target) override
return the distance coherence between the two points.
double weight_
the weight of coherence.
PointCoherence is a base class to compute coherence between the two points.
