Detailed Description

template<typename 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.

void itk::RegistrationParameterScalesFromJacobian< TMetric >::ComputeSampleStepScales	(	const ParametersType &	step,

protected

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

template<typename TMetric >

virtual::itk::LightObject::Pointer itk::RegistrationParameterScalesFromJacobian< TMetric >::CreateAnother ( ) 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.

void itk::RegistrationParameterScalesFromJacobian< TMetric >::EstimateScales ( ScalesType & scales )

overridevirtual

Estimate parameter scales.

template<typename TMetric >

FloatType itk::RegistrationParameterScalesFromJacobian< TMetric >::EstimateStepScale ( const ParametersType & step )

overridevirtual

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.
