Detailed Description

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

this class declares common interfaces for distance functions.

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

To use this function in the context of MembershipFunction, 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.

If users want to the distance between two points without setting the origin point. Use two argument version of Evaluate() function.
