Class DetectDescribeAssociateTwoPass<I extends boofcv.struct.image.ImageGray,Desc extends boofcv.struct.feature.TupleDesc>

java.lang.Object

boofcv.abst.feature.tracker.DetectDescribeAssociate<I,Desc>

boofcv.abst.feature.tracker.DetectDescribeAssociateTwoPass<I,Desc>

All Implemented Interfaces:

PointTracker<I>, PointTrackerTwoPass<I>

public class DetectDescribeAssociateTwoPass<I extends boofcv.struct.image.ImageGray,Desc extends boofcv.struct.feature.TupleDesc>
extends DetectDescribeAssociate<I,Desc>
implements PointTrackerTwoPass<I>

Changes behavior of DetectDescribeAssociate so that it conforms to the PointTrackerTwoPass interface. It can now take hints for where tracks might appear in the image. If possible AssociateDescription2D.setSource(org.ddogleg.struct.FastQueue, org.ddogleg.struct.FastQueue) will only be called once on the second pass.

Constructor Detail

DetectDescribeAssociateTwoPass

public DetectDescribeAssociateTwoPass(DdaFeatureManager<I,Desc> manager,
                                      boofcv.abst.feature.associate.AssociateDescription2D<Desc> associate,
                                      boofcv.abst.feature.associate.AssociateDescription2D<Desc> associate2,
                                      boolean updateDescription)

Configure the tracker. The parameters associate and associate2 can be the same instance.

Parameters:

manager - Feature manager

associate - Association algorithm for the first pass

associate2 - Association algorithm for the second pass

updateDescription - Should descriptions be updated? Typically false

Method Detail

process

public void process(I input)

Description copied from interface: PointTracker

Process input image and perform tracking.

Specified by:

process in interface PointTracker<I extends boofcv.struct.image.ImageGray>

Specified by:

process in interface PointTrackerTwoPass<I extends boofcv.struct.image.ImageGray>

Overrides:

process in class DetectDescribeAssociate<I extends boofcv.struct.image.ImageGray,Desc extends boofcv.struct.feature.TupleDesc>

Parameters:

input - Next image in the sequence

performSecondPass

public void performSecondPass()

Description copied from interface: PointTrackerTwoPass

Updates spacial information for each track and active list. Does not change the track description or any other lists. Can be called multiple times.

Specified by:

performSecondPass in interface PointTrackerTwoPass<I extends boofcv.struct.image.ImageGray>

finishTracking

public void finishTracking()

Description copied from interface: PointTrackerTwoPass

Finishes tracking and updates the track's description, updates inactive and drop track lists.

Specified by:

finishTracking in interface PointTrackerTwoPass<I extends boofcv.struct.image.ImageGray>

updateTrackLocation

protected void updateTrackLocation(org.ddogleg.struct.FastQueue<boofcv.struct.feature.AssociatedIndex> matches)

Update each track's location only and not its description. Update the active list too

setHint

public void setHint(double pixelX,
                    double pixelY,
                    PointTrack track)

Description copied from interface: PointTrackerTwoPass

Provides a hint for where the

Specified by:

setHint in interface PointTrackerTwoPass<I extends boofcv.struct.image.ImageGray>

Parameters:

pixelX - x-coordinate hint for where the track is in the image

pixelY - y-coordinate hint for where the track is in the image

track - The track for which the hint is being provided for
