Detailed Description

template<class TMetric>
class itk::RegistrationParameterScalesFromJacobian< TMetric >

Implements a registration helper class for estimating scales of transform parameters from Jacobian norms.

Its input includes the fixed/moving images and transform objects, which can be obtained from the metric object.

The scale of a parameter is estimated from the averaged squared norm of the Jacobian w.r.t the parameter. The averaging is done over a sampling of the image domain. The sampling by default is a uniform random distribution.

template<class TMetric >
void itk::RegistrationParameterScalesFromJacobian< TMetric >::ComputeSampleStepScales ( const ParametersType step,
ScalesType sampleScales 
)
protected

Compute the step scales for samples, i.e. the impacts on each sampled voxel from a change on the transform.

template<class TMetric >
virtual::itk::LightObject::Pointer itk::RegistrationParameterScalesFromJacobian< TMetric >::CreateAnother ( void  ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<class TMetric >
virtual void itk::RegistrationParameterScalesFromJacobian< TMetric >::EstimateLocalStepScales ( const ParametersType step,
ScalesType localStepScales 
)
virtual

Estimate the scales of local steps.

Implements itk::RegistrationParameterScalesEstimator< TMetric >.

template<class TMetric >
virtual void itk::RegistrationParameterScalesFromJacobian< TMetric >::EstimateScales ( ScalesType scales)
virtual

Estimate parameter scales.

Implements itk::RegistrationParameterScalesEstimator< TMetric >.

template<class TMetric >
virtual FloatType itk::RegistrationParameterScalesFromJacobian< TMetric >::EstimateStepScale ( const ParametersType step)
virtual

Estimate the scale for $\Delta p$, the step of change on parameters. The step scale describes the impact of $\Delta p$ on the transform.

Let us denote the transform by

\[ T(x, p) = T(x, p_0 + t * \Delta p) \]

where $x$ is the coordinates of a voxel, $p = p_0+t*\Delta p$ is the transform parameters, and $t$ is the step factor.

At a specific voxel at $x$, the step scale w.r.t. $\Delta p$ is defined here as

\[ |\frac{dT}{dt}| = |\frac{\partial T}{\partial p} * \Delta p |. \]

For multiple voxels, we average the above formula to get the overall step scale.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
