Member Function Documentation

◆ addTrackerFeature() [1/2]

bool cv::detail::tracking::TrackerContribFeatureSet::addTrackerFeature ( Ptr< TrackerContribFeature > &  feature)

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

Parameters
featureThe TrackerContribFeature class

◆ addTrackerFeature() [2/2]

bool cv::detail::tracking::TrackerContribFeatureSet::addTrackerFeature ( String  trackerFeatureType)

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

Parameters
trackerFeatureTypeThe TrackerContribFeature name

The modes available now:

  • "HAAR" – Haar Feature-based

The modes that will be available soon:

  • "HOG" – Histogram of Oriented Gradients features
  • "LBP" – Local Binary Pattern features
  • "FEATURE2D" – All types of Feature2D

Example TrackerContribFeatureSet::addTrackerFeature : :

//sample usage:
Ptr<TrackerContribFeature> trackerFeature = ...;
featureSet->addTrackerFeature( trackerFeature );
//or add CSC sampler with default parameters
//featureSet->addTrackerFeature( "HAAR" );
std::shared_ptr< _Tp > Ptr
Definition: cvstd_wrapper.hpp:23
Note
If you use the second method, you must initialize the TrackerContribFeature

◆ extraction()

void cv::detail::tracking::TrackerContribFeatureSet::extraction ( const std::vector< Mat > &  images)

Extract features from the images collection.

Parameters
imagesThe input images

◆ getResponses()

const std::vector< Mat > & cv::detail::tracking::TrackerContribFeatureSet::getResponses ( ) const

Get the responses.

Note
Be sure to call extraction before getResponses Example TrackerContribFeatureSet::getResponses : :

◆ getTrackerFeature()

const std::vector< std::pair< String, Ptr< TrackerContribFeature > > > & cv::detail::tracking::TrackerContribFeatureSet::getTrackerFeature ( ) const

◆ removeOutliers()

void cv::detail::tracking::TrackerContribFeatureSet::removeOutliers ( )

Remove outliers for all feature types (optional)

◆ selection()

void cv::detail::tracking::TrackerContribFeatureSet::selection ( )

Identify most effective features for all feature types (optional)
