Destructor.

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

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

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

sampler

The 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, [168] 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

image	The current frame
boundingBox	The bounding box from which regions can be calculated
