§ compute()

void cv::TrackerFeature::compute ( const std::vector< Mat > &  images,
Mat response 
)

Compute the features in the images collection.

Parameters
imagesThe images
responseThe output response

§ computeImpl()

virtual bool cv::TrackerFeature::computeImpl ( const std::vector< Mat > &  images,
Mat response 
)
protectedpure virtual

§ create()

static Ptr<TrackerFeature> cv::TrackerFeature::create ( const String trackerFeatureType)
static

Create TrackerFeature by tracker feature type.

Parameters
trackerFeatureTypeThe 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

§ getClassName()

String cv::TrackerFeature::getClassName ( ) const

Get the name of the specific TrackerFeature.

§ selection()

virtual void cv::TrackerFeature::selection ( Mat response,
int  npoints 
)
pure virtual

Identify most effective features.

Parameters
responseCollection of response for the specific TrackerFeature
npointsMax number of features
Note
This method modifies the response parameter

Implemented in cv::TrackerFeatureLBP, cv::TrackerFeatureHAAR, cv::TrackerFeatureHOG, and cv::TrackerFeatureFeature2d.
