Constructor & Destructor Documentation

LevelSetTracker	(	GridT &	grid,
		InterruptT *	interrupt = NULL
	)

Main constructor.

Exceptions

RuntimeError

if the grid is not a level set

LevelSetTracker

(

const LevelSetTracker< GridT, InterruptT > &

other

)

Shallow copy constructor called by tbb::parallel_for() threads during filtering.

Member Function Documentation

BOOST_STATIC_ASSERT

(

boost::is_floating_point< ValueType >::value

)

bool checkInterrupter ( )

inline

Returns

false if the process was interrupted

void dilate ( int  iterations = 1 )

inline

Fast but approximate dilation of the narrow band.

Note

This method works fine with low-order temporal and spatial schemes.

void endInterrupter ( )

inline

void erode ( int  iterations = 1 )

inline

Erodes the width of the narrow-band and update the background values.

Exceptions

ValueError

if iterations is larger then the current half-width.

int getGrainSize ( ) const

inline

Returns

the grain-size used for multi-threading

int getNormCount ( ) const

inline

Returns

The number of normalizations performed per track or normalize call.

math::BiasedGradientScheme getSpatialScheme ( ) const

inline

Returns

the spatial finite difference scheme

math::TemporalIntegrationScheme getTemporalScheme ( ) const

inline

Returns

the temporal integration scheme

const GridType& grid ( ) const

inline

LeafManagerType& leafs ( )

inline

const LeafManagerType& leafs ( ) const

inline

void normalize

(

const MaskType *

mask

)

Iterative normalization, i.e. solving the Eikonal equation.

Note

The mask it optional and by default it is ignored.

void normalize ( )

inline

Iterative normalization, i.e. solving the Eikonal equation.

void normalize ( const MaskT *  mask )

inline

void prune ( )

inline

Remove voxels that are outside the narrow band. (substep of track)

void setGrainSize ( int  grainsize )

inline

Set the grain-size used for multi-threading.

Note

A grainsize of 0 or less disables multi-threading!

void setNormCount ( int  n )

inline

Set the number of normalizations performed per track or normalize call.

void setSpatialScheme ( math::BiasedGradientScheme  scheme )

inline

Set the spatial finite difference scheme.

void setTemporalScheme ( math::TemporalIntegrationScheme  scheme )

inline

Set the spatial finite difference scheme.

void startInterrupter ( const char *  msg )

inline

void track ( )

inline

Track the level set interface, i.e. rebuild and normalize the narrow band of the level set.

ValueType voxelSize ( ) const
