Member Function Documentation

§ addTrackerSamplerAlgorithm() [1/2]

bool cv::TrackerSampler::addTrackerSamplerAlgorithm ( String  trackerSamplerAlgorithmType)

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

Parameters
trackerSamplerAlgorithmTypeThe 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

§ addTrackerSamplerAlgorithm() [2/2]

bool cv::TrackerSampler::addTrackerSamplerAlgorithm ( Ptr< TrackerSamplerAlgorithm > &  sampler)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters
samplerThe TrackerSamplerAlgorithm

§ getSamplers()

const std::vector<std::pair<String, Ptr<TrackerSamplerAlgorithm> > >& cv::TrackerSampler::getSamplers ( ) const

Return the collection of the TrackerSamplerAlgorithm.

§ getSamples()

const std::vector<Mat>& cv::TrackerSampler::getSamples ( ) const

Return the samples from all TrackerSamplerAlgorithm, [156] Fig. 1 variable Sk.

§ sampling()

void cv::TrackerSampler::sampling ( const Mat image,
Rect  boundingBox 
)

Computes the regions starting from a position in an image.

Parameters
imageThe current frame
boundingBoxThe bounding box from which regions can be calculated
