 Class<T> imageType)

Method Details

initialize

public boolean initialize(T image,
 Quadrilateral_F64 location)

Description copied from interface: TrackerObjectQuad

Initializes tracking by specifying the object's location using a quadrilateral. Some implementations can fail if there is insufficient visual information for it to track. All previous tracking information is discarded when this function is called.

Specified by:

initialize in interface TrackerObjectQuad<T extends ImageGray<T>>

Parameters:

image - Initial image in the sequence

location - Initial location of the object being tracked

Returns:

true if successful and false if not.

hint

public void hint(Quadrilateral_F64 hint)

Doesn't support hint because it does a forwards and backwards track. Adding hint isn't trivial. To add it a forward/reverse transform needs to be added

Specified by:

hint in interface TrackerObjectQuad<T extends ImageGray<T>>

Parameters:

hint - (Input) estimated location of the object.

process

public boolean process(T image,
 Quadrilateral_F64 results)

Description copied from interface: TrackerObjectQuad

Updates the tracks location using the latest video frame. TrackerObjectQuad.initialize(boofcv.struct.image.ImageBase, Quadrilateral_F64) must be called once before this function can be called.

Specified by:

process in interface TrackerObjectQuad<T extends ImageGray<T>>

Parameters:

image - (Input) The next image in the video sequence.

results - (Output) Storage for new location if tracking is successful.

Returns:

true if the target was found and 'location' updated.

getImageType

public ImageType<T> getImageType()

Description copied from interface: TrackerObjectQuad

Returns information on the type of image that it can process.

Specified by:

getImageType in interface TrackerObjectQuad<T extends ImageGray<T>>

Returns:

Image type

quadToRectRot

public static void quadToRectRot(Quadrilateral_F64 q,
 RectangleRotate_F64 r)

quadToRectRot

public static void quadToRectRot(Quadrilateral_F64 q,
 RectangleRotate_F32 r)

rectRotToQuad

public static void rectRotToQuad(RectangleRotate_F64 r,
 Quadrilateral_F64 q)

rectRotToQuad

public static void rectRotToQuad(RectangleRotate_F32 r,
 Quadrilateral_F64 q)

getLowLevelTracker

public SparseFlowObjectTracker<T,D> getLowLevelTracker()

Description copied from interface: TrackerObjectQuad

Provides access to the inner low level tracker. You need to be familiar with the tracker's source code to make sure of this function. Returns null if implementing it doesn't make sense.

Specified by:

getLowLevelTracker in interface TrackerObjectQuad<T extends ImageGray<T>>

Returns:

Tracking algorithm.
