Constructor Detail

Sfot_to_TrackObjectQuad

public Sfot_to_TrackObjectQuad(SparseFlowObjectTracker<T,D> alg,
                               java.lang.Class<T> imageType)

Method Detail

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>

Parameters:

image - Initial image in the sequence

location - Initial location of the object being tracked

Returns:

true if successful and false if not.

process

public boolean process(T image,
                       Quadrilateral_F64 location)

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>

Parameters:

image - The next image in the video sequence.

location - The new location of the object being tracked.

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>

Returns:

Image type
