Detailed Description

Class that manages the extraction and selection of features.

[189] Feature Extraction and Feature Set Refinement (Feature Processing and Feature Selection). See table I and section III C [132] Appearance modelling -> Visual representation (Table II, section 3.1 - 3.2)

TrackerFeatureSet is an aggregation of TrackerFeature

Member Function Documentation

addTrackerFeature() [1/2]

bool cv::TrackerFeatureSet::addTrackerFeature

(

String

trackerFeatureType

)

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

Parameters

trackerFeatureType

The TrackerFeature 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 TrackerFeatureSet::addTrackerFeature : :

//sample usage:

Ptr<TrackerFeature> trackerFeature = new TrackerFeatureHAAR( HAARparameters );
featureSet->addTrackerFeature( trackerFeature );

//or add CSC sampler with default parameters
//featureSet->addTrackerFeature( "HAAR" );

Note

If you use the second method, you must initialize the TrackerFeature

addTrackerFeature() [2/2]

bool cv::TrackerFeatureSet::addTrackerFeature

(

Ptr< TrackerFeature > &

feature

)

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

Parameters

feature

The TrackerFeature class

extraction()

void cv::TrackerFeatureSet::extraction

(

const std::vector< Mat > &

images

)

Extract features from the images collection.

Parameters

images

The input images

getResponses()

const std::vector<Mat>& cv::TrackerFeatureSet::getResponses

(

)

const

Get the responses.

Note

Be sure to call extraction before getResponses Example TrackerFeatureSet::getResponses : :

getTrackerFeature()

const std::vector<std::pair<String, Ptr<TrackerFeature> > >& cv::TrackerFeatureSet::getTrackerFeature

(

)

const

Get the TrackerFeature collection (TrackerFeature name, TrackerFeature pointer)

removeOutliers()

void cv::TrackerFeatureSet::removeOutliers

(

)

Remove outliers for all feature types (optional)

selection()

void cv::TrackerFeatureSet::selection

(

)

Identify most effective features for all feature types (optional)
