Detailed Description

template<typename TFixedPointSet, typename TMovingPointSet, typename TDistanceMap = itk::Image<unsigned short, TMovingPointSet::PointDimension>>
class itk::EuclideanDistancePointMetric< TFixedPointSet, TMovingPointSet, TDistanceMap >

Computes the minimum distance between a moving point-set and a fixed point-set. A vector of minimum closest point distance is created for each point in the moving point-set. No correspondence is needed. For speed consideration, the point-set with the minimum number of points should be used as the moving point-set. If the number of points is high, the possibility of setting a distance map should improve the speed of the closest point computation.
