Detailed Description

template<typename TMetric>
class itk::RegistrationParameterScalesFromShiftBase< TMetric >

Registration helper base class for estimating scales of transform parameters from the maximum voxel shift caused by a parameter change.

Derived classes provide estimation using physical or index space.

The scale of a parameter is estimated from the maximum voxel shift produced from a small variation of this parameter. The maximization is done by checking sample points within the metric's virtual domain. Sample points are generated differently depending on the type of metric transform or metric type. See RegistrationParameterScalesEstimator documentation.
