Detailed Description

Dijkstra algorithm to compute the graph geodesic.

Takes as input a polyline and an image representing a 2D cost function and performs a single source shortest path calculation. Dijkstra's algorithm is used. The implementation is similar to the one described in Introduction to Algorithms (Second Edition) by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Cliff Stein, published by MIT Press and McGraw-Hill. Some minor enhancement are added though. All vertices are not pushed on the heap at start, instead a front set is maintained. The heap is implemented as a binary heap. The output of the filter is a set of lines describing the shortest path from StartVertex to EndVertex. See parent class vtkDijkstraGraphGeodesicPath for the implementation.

Warning
The input cost image must have only VTK_PIXEL cells: i.e., a 2D image or slice of a 3D volume. A cost function for a gray scale image might be generated by the following pipeline: vtkImageData->vtkImageGradientMagnitude->vtkImageShiftScale wherein the gradient magnitude image is inverted so that strong edges have low cost value. Costs in moving from a vertex v to a vertex u are calculated using a weighted additive scheme: cost = Iw*f(I) + Ew*f(u,v) + Cw*f(t,u,v) where Iw is the weight associated with f(I): the normalized image cost, Ew is the weight associated with f(u,v): the normalized distance between vertices u and v, and Cw is the weight associated with f(t,u,v): the normalized curvature calculated from the vertex t which precedes vertex u, and vertices u and v. All weights range from 0 to 1.

Member Function Documentation

◆ New()

static vtkDijkstraImageGeodesicPath* vtkDijkstraImageGeodesicPath::New ( )
static

Instantiate the class.

◆ IsTypeOf()

static vtkTypeBool vtkDijkstraImageGeodesicPath::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkDijkstraImageGeodesicPath::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ SafeDownCast()

static vtkDijkstraImageGeodesicPath* vtkDijkstraImageGeodesicPath::SafeDownCast ( vtkObjectBase o)
static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkDijkstraImageGeodesicPath::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ NewInstance()

vtkDijkstraImageGeodesicPath* vtkDijkstraImageGeodesicPath::NewInstance ( ) const

◆ PrintSelf()

void vtkDijkstraImageGeodesicPath::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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.

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ SetInputData()

void vtkDijkstraImageGeodesicPath::SetInputData ( vtkDataObject )

Specify the image object which is used as a cost function.

◆ GetInputAsImageData()

vtkImageData* vtkDijkstraImageGeodesicPath::GetInputAsImageData ( )

◆ SetImageWeight()

void vtkDijkstraImageGeodesicPath::SetImageWeight ( double  )

Image cost weight.

◆ GetImageWeight()

virtual double vtkDijkstraImageGeodesicPath::GetImageWeight ( )
virtual

◆ SetEdgeLengthWeight()

void vtkDijkstraImageGeodesicPath::SetEdgeLengthWeight ( double  )

Edge length cost weight.

◆ GetEdgeLengthWeight()

virtual double vtkDijkstraImageGeodesicPath::GetEdgeLengthWeight ( )
virtual

◆ SetCurvatureWeight()

virtual void vtkDijkstraImageGeodesicPath::SetCurvatureWeight ( double  )
virtual

Curvature cost weight.

◆ GetCurvatureWeight()

virtual double vtkDijkstraImageGeodesicPath::GetCurvatureWeight ( )
virtual

◆ FillInputPortInformation()

int vtkDijkstraImageGeodesicPath::FillInputPortInformation ( int  port,
vtkInformation info 
)
overrideprotectedvirtual

Fill the input port information objects for this algorithm.

This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPolyDataAlgorithm.

◆ RequestData()

int vtkDijkstraImageGeodesicPath::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ BuildAdjacency()

void vtkDijkstraImageGeodesicPath::BuildAdjacency ( vtkDataSet inData)
overrideprotectedvirtual

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ UpdateStaticCosts()

protected

◆ CalculateStaticEdgeCost()

double vtkDijkstraImageGeodesicPath::CalculateStaticEdgeCost ( vtkDataSet inData,
vtkIdType  u,
vtkIdType  v 
)
overrideprotectedvirtual

Reimplemented from vtkDijkstraGraphGeodesicPath.

◆ CalculateDynamicEdgeCost()

double vtkDijkstraImageGeodesicPath::CalculateDynamicEdgeCost ( vtkDataSet inData,
vtkIdType  u,
vtkIdType  v 
)
