Detailed Description

Vessel - vessel registration algorithm.

Input is two centerline representations of vessel trees. Output is either a linear transform or a nonlinear transform (nonlinear not used yet).

Basic usage: Run execute(), then get result with getLinearTransform()

Member Function Documentation

void cx::SeansVesselReg::checkQuality ( Transform3D  linearTransform)

Analyze 'size' of transform. Warn if too far away from an identity matrix.

Definition at line 954 of file SeansVesselReg.cxx.

void cx::SeansVesselReg::computeDistances ( ContextPtr  context = ContextPtr())

Compute distances between the two datasets.

The results will be added into the context: sorted source and target points, and the metric.

SeansVesselReg::ContextPtr cx::SeansVesselReg::createContext ( DataPtr  source,
DataPtr  target

vtkPointsPtr cx::SeansVesselReg::createSortedPoints ( vtkIdListPtr  sortedIDList,
vtkPointsPtr  unsortedPoints,
int  numPoints 
)
protected

Using the already sorted list of point ID's, create a sorted list of points based on the numPoint first of unsortedPoints.

Definition at line 417 of file SeansVesselReg.cxx.

vtkPolyDataPtr cx::SeansVesselReg::crop ( vtkPolyDataPtr  input,
vtkPolyDataPtr  fixed,
double  margin 
)
protected

Crop the input data using a bounding box generated from the fixed data. The margin is used to enlarge the bounding box.

Definition at line 617 of file SeansVesselReg.cxx.

bool cx::SeansVesselReg::execute ( )

Execute the vessel to vessel registration. The result is available via the getLinearResult().

source is moving and target is fixed

vtkPolyDataPtr cx::SeansVesselReg::extractPolyData ( ImagePtr  image,
int  p_neighborhoodFilterThreshold,
double  p_BoundingBox[6] 
)
static

Extract polydata from a image.

Parameters
image
p_neighborhoodFilterThreshold
p_BoundingBox
Returns

Input an image representation of centerlines. Transform to polydata, reject all data outside bounding box, unknown parameter: p_neighborhoodFilterThreshold

void cx::SeansVesselReg::performOneRegistration ( ContextPtr  context,
bool  linear 
)

Register the source points to the target point in a single ste.

Use the source to find the closest points on the target set, then register using either a landmark transform or a thinplatetransform. The context source points will be updated with the new transformation.

If sorted points are available in the context, they are used instead of computing new ones. The sorted data will always be cleared at the end of this method, This is because we want to call it iteratively.
