class GradientBalloonInrimageInformation : public RangeInformation

a class that store all information necessary for computing an external force based on the gradient of the gradient norm and a ballon force

Inheritance:

Public Classes

enum	OrientationConstraint test gradient orientation constraint NONE accept all voxels ALONG_GRADIENT accept only voxels whose gradient orientation match line orientation ALONG_OPPOSITE_GRADIENT accept only voxels whose gradient orientation match opposite line orientation

Public Fields

static const TclString

informationName name stored in the Range Information

Public Methods

double	getThreshold () const get the gradient threshold
void	setThreshold (const double threshold) set the gradient threshold
OrientationConstraint	getOrientationConstraint () const get the gradient constraint
void	setOrientationConstraint (const OrientationConstraint constraint) set the gradient constraint
double	getBalloonForce () const returns the normal displacement used to compute the gradient balloon Force
void	setBalloonForce (const double force) sets the normal displacement used to compute the gradient balloon Force
static RangeInformation*	readGradientBalloonInformation (GFInput &input) create a gradient of the gradient information Object from a file
virtual RangeInformation*	duplicate () create a copy of this region information object
virtual void	writeInFile (GFOutput &output) write in a file the data stored in a gradient of the gradient information object

Public

	constructor GradientBalloonInrimageInformation (double _gradientThreshold = 0.0, OrientationConstraint _gradientConstraint = NONE, double _balloonForce=0.0) builds a data structure for a force computed as the gradient of gradient norm : requires a gradient threshold and its orientation constraint
	destructor virtual ~GradientBalloonInrimageInformation () destroys the object

Protected Fields

double	gradientThreshold the gradient norm value above which a voxel is considered for test
OrientationConstraint	gradientConstraint if there is a constraint on the voxel gradient orientation
double	balloonForce the maximum displacement allowed in the normal direction

static const TclString informationName

name stored in the Range Information

enum OrientationConstraint

test gradient orientation constraint

NONE

accept all voxels

ALONG_GRADIENT

accept only voxels whose gradient orientation match line orientation

ALONG_OPPOSITE_GRADIENT

accept only voxels whose gradient orientation match opposite line orientation

double gradientThreshold

the gradient norm value above which a voxel is considered for test

OrientationConstraint gradientConstraint

if there is a constraint on the voxel gradient orientation

the maximum displacement allowed in the normal direction

constructor

GradientBalloonInrimageInformation(double _gradientThreshold = 0.0, OrientationConstraint _gradientConstraint = NONE, double _balloonForce=0.0)

builds a data structure for a force computed as the gradient of gradient norm : requires a gradient threshold and its orientation constraint

Parameters:

_gradientThreshold - the threshold on the gradient norm value
_gradientConstraint - the side on which to look for the region
_balloonForce - the maximum displacement allowed in the normal direction

destructor

virtual ~GradientBalloonInrimageInformation()

destroys the object

double getThreshold() const

get the gradient threshold

void setThreshold(const double threshold)

set the gradient threshold

OrientationConstraint getOrientationConstraint() const

get the gradient constraint

void setOrientationConstraint(const OrientationConstraint constraint)

set the gradient constraint

double getBalloonForce() const

returns the normal displacement used to compute the gradient balloon Force

void setBalloonForce(const double force)

sets the normal displacement used to compute the gradient balloon Force

static RangeInformation* readGradientBalloonInformation(GFInput &input)

create a gradient of the gradient information Object from a file

virtual RangeInformation* duplicate()
