Detailed Description

template<typename TFixedPointSet, typename TMovingPointSet = TFixedPointSet, class TInternalComputationValueType = double>
class itk::ExpectationBasedPointSetToPointSetMetricv4< TFixedPointSet, TMovingPointSet, TInternalComputationValueType >

Computes an expectation-based metric between two point sets.

This information-theoretic point set measure models each point set as a sum of Gaussians. To speed up computation, evaluation of the local value/derivative is done in a user-specified neighborhood using the k-d tree constructed in the superclass.
