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()

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.

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.
