Detailed Description

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

Like sum of squared difference between point sets, except you throw away a certain percentage of outliers.

This measure was implemented in section 2.2 equation 1 of Ourselin et. al. MICCAI 2000, "Block Matching: a general framework..." Given two corresponding point sets, we compute the sum of squared difference of the smallest h% percentage. This will throw away gross outliers.
