protectedpure virtual

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

create()

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

static

Create TrackerFeature by tracker feature type.

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

getClassName()

(

)

const

Get the name of the specific TrackerFeature.

selection()

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

pure virtual
