itk::Statistics::DistanceToCentroidMembershipFunction< TVector > Class Template Reference

#include <itkDistanceToCentroidMembershipFunction.h>

Detailed Description

template<typename TVector>
class itk::Statistics::DistanceToCentroidMembershipFunction< TVector >

DistanceToCentroidMembershipFunction models class membership using a distance metric.

DistanceToCentroidMembershipFunction is a subclass of MembershipFunctionBase that models class membership using the distance to the centroid of the class. A choice of distance metric can be specified using the SetDistanceMetric() method. Options include EuclideanDistanceMetric, EuclideanSquaredDistanceMetric, and ManhattanDistanceMetric. The centroid of the class is specified using the SetCentroid() method. Any other parameters to control the distance function evaluation have to be set directly on the distance function itself.
