Detailed Description

template<typename TLevelSet, typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>
class itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >

Generates the upwind gradient field of fast marching arrival times.

This filter adds some extra functionality to its base class. While the solution T(x) of the Eikonal equation is being generated by the base class with the fast marching method, the filter generates the upwind gradient vectors of T(x), storing them in an image.

Since the Eikonal equation generates the arrival times of a wave traveling at a given speed, the generated gradient vectors can be interpreted as the slowness (1/velocity) vectors of the front (the quantity inside the modulus operator in the Eikonal equation).

Gradient vectors are computed using upwind finite differences, that is, information only propagates from points where the wavefront has already passed. This is consistent with how the fast marching method works.

One more extra feature is the possibility to define a set of Target points where the propagation stops. This can be used to avoid computing the Eikonal solution for the whole domain. The front can be stopped either when one Target point is reached or all Target points are reached. The propagation can stop after a time TargetOffset has passed since the stop condition is met. This way the solution is computed a bit downstream the Target points, so that the level sets of T(x) corresponding to the Target are smooth.

For an alternative implementation, see itk::FastMarchingUpwindGradientImageFilterBase.

overrideprotectedvirtual

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.

template<typename TLevelSet , typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>

virtual void itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >::SetGenerateGradientImage ( bool _arg )

template<typename TLevelSet , typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>

virtual void itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >::SetTargetOffset ( double _arg )

virtual

Set how long (in terms of arrival times) after targets are reached the front must stop. This is useful to ensure that the level set of target arrival time is smooth.

template<typename TLevelSet , typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>

void itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >::SetTargetPoints ( NodeContainer * points )

inline

Backwards compatibility for enum values Set the container of Target Points. If a target point is reached, the propagation stops. Trial points are represented as a VectorContainer of LevelSetNodes.

◆ VerifyPreconditions()

template<typename TLevelSet , typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>

virtual void itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >::VerifyPreconditions ( )

overrideprotectedvirtual

Verifies that the process object has been configured correctly, that all required inputs are set, and needed parameters are set appropriately. If not valid an exceptions will be thrown.

This method is called before UpdateOutputInformation() is propagated to the inputs.

The ProcessObject's implementation verifies that the m_NumberOfRequiredInputs are set and not null.

Reimplemented from itk::ProcessObject.

◆ VerifyTargetReachedModeConditions()

template<typename TLevelSet , typename TSpeedImage = Image<float, TLevelSet::ImageDimension>>

void itk::FastMarchingUpwindGradientImageFilter< TLevelSet, TSpeedImage >::VerifyTargetReachedModeConditions ( unsigned int targetModeMinPoints = 1 ) const

inlineprotected

Check that the conditions to set the target reached mode are satisfied.

The sufficient target point count is 1 for TargetConditionEnum::OneTarget and TargetConditionEnum::AllTargets
modes; and it is given by a particular value for the TargetConditionEnum::SomeTargets mode.

Raises an exception if the conditions are not satisfied.
