(

)

Destructor.

Member Function Documentation

addTrackerSamplerAlgorithm() [1/2]

bool cv::detail::tracking::TrackerContribSampler::addTrackerSamplerAlgorithm

(

Ptr< TrackerContribSamplerAlgorithm > &

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 TrackerContribSamplerAlgorithm

addTrackerSamplerAlgorithm() [2/2]

bool cv::detail::tracking::TrackerContribSampler::addTrackerSamplerAlgorithm

(

String

trackerSamplerAlgorithmType

)

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

Parameters

trackerSamplerAlgorithmType

The TrackerContribSamplerAlgorithm name

The modes available now:

• "CSC" – Current State Center
• "CS" – Current State
• "PF" – Particle Filtering

Example TrackerContribSamplerAlgorithm::addTrackerContribSamplerAlgorithm : :

TrackerContribSamplerCSC::Params CSCparameters;
Ptr<TrackerContribSamplerAlgorithm> CSCSampler = new TrackerContribSamplerCSC( 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 TrackerContribSamplerAlgorithm

getSamplers()

const std::vector< std::pair< String, Ptr< TrackerContribSamplerAlgorithm > > > & cv::detail::tracking::TrackerContribSampler::getSamplers

(

)

const

Return the collection of the TrackerContribSamplerAlgorithm.

getSamples()

const std::vector< Mat > & cv::detail::tracking::TrackerContribSampler::getSamples

(

)

const

Return the samples from all TrackerContribSamplerAlgorithm, [232] Fig. 1 variable Sk.

sampling()

void cv::detail::tracking::TrackerContribSampler::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
