Detailed Description

template<class TFixedPointSet, class TMovingPointSet>
class itk::PointSetToPointSetMetricv4< TFixedPointSet, TMovingPointSet >

Computes similarity between two point sets.

This class is templated over the type of the two point-sets. It expects a Transform to be plugged in for each of fixed and moving point sets. The transforms default to IdenityTransform types. This particular class is the base class for a hierarchy of point-set to point-set metrics.

This class computes a value that measures the similarity between the fixed point-set and the moving point-set in the moving domain. The fixed point set is transformed into the virtual domain by computing the inverse of the fixed transform, then transformed into the moving domain using the moving transform.

Since the PointSet class permits each Point to be associated with a PixelType, there are potential applications which could make use of this additional information. For example, the derived LabeledPointSetToPointSetMetric class uses the PixelType as a LabelType for estimating total metric values and gradients from the individual label-wise point subset metric and derivatives

If a virtual domain is not defined by the user, one of two things happens: 1) If the moving transform is a global type, then the virtual domain is left undefined and every point is considered to be within the virtual domain. 2) If the moving transform is a local-support type, then the virtual domain is taken during initialization from the moving transform displacement field, and all fixed points are verified to be within the virtual domain after transformation by the inverse fixed transform. Points outside the virtual domain are not used. See GetNumberOfValidPoints() to verify how many fixed points were used during evaluation.

See ObjectToObjectMetric documentation for more discussion on the virutal domain.

Note: When used with an RegistrationParameterScalesEstimator estimator, a VirtualDomainPointSet must be defined and assigned to the estimator, for use in shift estimation. The virtual domain point set can be retrieved from the metric using the GetVirtualTransformedPointSet() method.
