Field Detail

octave

protected OCTAVE extends Octave<?,?,IMAGE> octave

The current octave.

currentScaleIndex

protected int currentScaleIndex

The index of the scale currently being processed within the octave. This should be changed as the finder progresses through the scales.

listener

protected OctaveInterestPointListener<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>> listener

The listener object that gets informed when interest points are detected.

AbstractOctaveInterestPointFinder

public AbstractOctaveInterestPointFinder()

Method Detail

getOctave

public OCTAVE getOctave()

Description copied from interface: OctaveInterestPointFinder

Get the octave from which we are operating

Specified by:

getOctave in interface OctaveInterestPointFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>

Returns:

the octave

getCurrentScaleIndex

public int getCurrentScaleIndex()

Description copied from interface: OctaveInterestPointFinder

Get the current scale index within the octave. Index 0 is the first level of the octave.

Specified by:

getCurrentScaleIndex in interface OctaveInterestPointFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>

Returns:

the current scale index.

setOctaveInterestPointListener

public void setOctaveInterestPointListener(OctaveInterestPointListener<OCTAVE,IMAGE> listener)

Description copied from interface: OctaveInterestPointFinder

Set a listener object that will listen to events triggered when interest points are detected.

Specified by:

setOctaveInterestPointListener in interface OctaveInterestPointFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>

Parameters:

listener - the listener

getOctaveInterestPointListener

public OctaveInterestPointListener<OCTAVE,IMAGE> getOctaveInterestPointListener()

Description copied from interface: OctaveInterestPointFinder

Get the current listener object.

Specified by:

getOctaveInterestPointListener in interface OctaveInterestPointFinder<OCTAVE extends Octave<?,?,IMAGE>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>

Returns:

the listener, or null if none set.
