Detailed Description

template<unsigned int VDimension>
class itk::PolyLineParametricPath< VDimension >

Represent a path of line segments through ND Space.

This class is intended to represent parametric paths through an image, where the paths are composed of line segments. Each line segment traverses one unit of input. A classic application of this class is the representation of contours in 2D images, especially when the contours only need to be approximately correct. Another use of a path is to guide the movement of an iterator through an image.

Member Function Documentation

◆ AddVertex()

template<unsigned int VDimension>

void itk::PolyLineParametricPath< VDimension >::AddVertex ( const ContinuousIndexType & vertex )

inline

Evaluate the first derivative of the ND output with respect to the 1D input. This is an exact, algebraic function. Add a vertex (and a connecting line segment to the previous vertex). Adding a vertex has the additional effect of extending the domain of the PolyLineParametricPath by 1.0 (each pair of consecutive vertices is separated by one unit of input).

Definition at line 100 of file itkPolyLineParametricPath.h.

◆ CreateAnother()

template<unsigned int VDimension>

virtual::itk::LightObject::Pointer itk::PolyLineParametricPath< VDimension >::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.

◆ EndOfInput()

template<unsigned int VDimension>

InputType itk::PolyLineParametricPath< VDimension >::EndOfInput ( ) const

inlineoverridevirtual

Where does the path end? This value is necessary for IncrementInput() to know how to go to the end of a path. Since each line segment covers one unit of input, this is the number of vertices - 1.

Reimplemented from itk::Path< double, ContinuousIndex< SpacePrecisionType, VDimension >, VDimension >.

Definition at line 111 of file itkPolyLineParametricPath.h.

◆ Evaluate()

template<unsigned int VDimension>

OutputType itk::PolyLineParametricPath< VDimension >::Evaluate ( const InputType & input ) const

overridevirtual

Return the location of the parametric path at the specified location.

Implements itk::Path< double, ContinuousIndex< SpacePrecisionType, VDimension >, VDimension >.

◆ EvaluateDerivative()

template<unsigned int VDimension>

VectorType itk::PolyLineParametricPath< VDimension >::EvaluateDerivative ( const InputType & input ) const

overridevirtual

This function overrides the superclass EvaluateDerivative and instead calculates the instantaneous derivative of input by taking the index of the previous and next integral timepoints and subtracting them

Reimplemented from itk::ParametricPath< VDimension >.

◆ GetModifiableVertexList()

template<unsigned int VDimension>

virtual VertexListType * itk::PolyLineParametricPath< VDimension >::GetModifiableVertexList ( )

virtual

Return the container of Vertices as a const object.

◆ GetNameOfClass()

template<unsigned int VDimension>

const char * itk::PolyLineParametricPath< VDimension >::GetNameOfClass ( ) const

overridevirtual

See also: LightObject::GetNameOfClass()

Reimplemented from itk::ParametricPath< VDimension >.

◆ GetVertexList()

template<unsigned int VDimension>

virtual const VertexListType * itk::PolyLineParametricPath< VDimension >::GetVertexList ( ) const

virtual

◆ IncrementInput()

template<unsigned int VDimension>

OffsetType itk::PolyLineParametricPath< VDimension >::IncrementInput ( InputType & input ) const

overridevirtual

This function overrides the superclass IncrementInput and calculates the next pixel along the path to visit by using the instantaneous partial derivatives to calculate the timestep needed to move along the path by one pixel

Reimplemented from itk::ParametricPath< VDimension >.

◆ Initialize()

template<unsigned int VDimension>

void itk::PolyLineParametricPath< VDimension >::Initialize ( )

inlineoverridevirtual

Needed for Pipelining

Reimplemented from itk::DataObject.

Definition at line 121 of file itkPolyLineParametricPath.h.

◆ New()

template<unsigned int VDimension>

static Pointer itk::PolyLineParametricPath< VDimension >::New ( )

static

New() method for dynamic construction

◆ PrintSelf()

template<unsigned int VDimension>

void itk::PolyLineParametricPath< VDimension >::PrintSelf	(	std::ostream &	os,
		Indent	indent ) const

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.
