Method Detail

compute

public void compute(@Const @ByRef
                    MatVector images,
                    @ByRef
                    Mat response)

\brief Compute the features in the images collection

Parameters:

images - The images

response - The output response

create

@opencv_core.Ptr
 @ByVal
public static TrackerFeature create(@opencv_core.Str
                                                             BytePointer trackerFeatureType)

\brief 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

create
