Constructor Details

AssociateGreedyBase2D

protected AssociateGreedyBase2D(ScoreAssociation<D> scoreAssociation,
 AssociateImageDistanceFunction distanceFunction)

Specifies score mechanism

Parameters:

scoreAssociation - How features are scored.

Method Details

init

public void init(int imageWidth,
 int imageHeight)

Initializes data structures. Must call before associate()

Parameters:

imageWidth - Width of input image

imageHeight - Height of input image

setSource

public void setSource(FastAccess<Point2D_F64> location,
 FastAccess<D> descriptions)

setDestination

public void setDestination(FastAccess<Point2D_F64> location,
 FastAccess<D> descriptions)

associate

public abstract void associate()

Performs association by computing a 2D score matrix and discarding matches which fail max distance check. See AssociateGreedyBase for a full description.
