Constructor Detail

TrackerSampler

public TrackerSampler(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

TrackerSampler

public TrackerSampler(long size)

Native array allocator. Access with Pointer.position(long).

TrackerSampler

public TrackerSampler()

\brief Constructor

Method Detail

position

public TrackerSampler position(long position)

Overrides:

position in class Pointer

sampling

public void sampling(@Const @ByRef
                     Mat image,
                     @ByVal
                     Rect boundingBox)

\brief Computes the regions starting from a position in an image

Parameters:

image - The current frame

boundingBox - The bounding box from which regions can be calculated

getSamplers

@Const
 @ByRef
public StringTrackerSamplerAlgorithmPairVector getSamplers()

\brief Return the collection of the TrackerSamplerAlgorithm

getSamples

@Const
 @ByRef
public MatVector getSamples()

\brief Return the samples from all TrackerSamplerAlgorithm, \cite AAM Fig. 1 variable Sk

addTrackerSamplerAlgorithm

@Cast(value="bool")
public boolean addTrackerSamplerAlgorithm(@opencv_core.Str
                                                              BytePointer trackerSamplerAlgorithmType)

\brief Add TrackerSamplerAlgorithm in the collection. Return true if sampler is added, false otherwise

Parameters:

trackerSamplerAlgorithmType - The TrackerSamplerAlgorithm name

The modes available now: - "CSC" -- Current State Center - "CS" -- Current State - "PF" -- Particle Filtering

Example TrackerSamplerAlgorithm::addTrackerSamplerAlgorithm : :

         TrackerSamplerCSC::Params CSCparameters;
         Ptr<TrackerSamplerAlgorithm> CSCSampler = new TrackerSamplerCSC( CSCparameters );

         if( !sampler->addTrackerSamplerAlgorithm( CSCSampler ) )
           return false;

         //or add CSC sampler with default parameters
         //sampler->addTrackerSamplerAlgorithm( "CSC" );
    

\note If you use the second method, you must initialize the TrackerSamplerAlgorithm
