Detailed Description

template<class TVector>
class itk::Statistics::DistanceMetric< TVector >

this class declares common interfaces for distance functions.

As a function derived from FunctionBase, users use Evaluate method to get result.

To use this function users should first set the origin by calling SetOrigin() function, then call Evaluate() method with a point to get the distance between the origin point and the evaluation point.

template<class TVector>
virtual double itk::Statistics::DistanceMetric< TVector >::Evaluate ( const MeasurementVectorType x1,
const MeasurementVectorType x2 
) const
pure virtual

Gets the distance between x1 and x2. This method is used by KdTreeKMeans estimators. When the estimator is refactored, this method should be removed. Distance between two measurement vectors can be computed by setting one of them as an origin of the distane and using the Evaluate method with a single argument

Implemented in itk::Statistics::MahalanobisDistanceMetric< TVector >, itk::Statistics::ManhattanDistanceMetric< TVector >, itk::Statistics::EuclideanDistanceMetric< TVector >, itk::Statistics::EuclideanDistanceMetric< ParameterType >, and itk::Statistics::EuclideanSquareDistanceMetric< TVector >.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.

template<class TVector>
void itk::Statistics::DistanceMetric< TVector >::SetOrigin ( const OriginType x)

Sets the origin point that will be used for the single point version Evaluate() function. This function is necessary part of implementing the Evaluate() interface. The argument of SetOrigin() must be of type DistanceMetric::OriginType, which in most cases will be different from the TVector type. This is necessary because often times the origin would be a mean, or a vector representative of a collection of vectors.
