Member Function Documentation

§ collectGarbage()

virtual void cv::detail::FeaturesFinder::collectGarbage ( )
inlinevirtual

Frees unused memory allocated before if there is any.

§ find()

virtual void cv::detail::FeaturesFinder::find ( InputArray  image,
ImageFeatures features 
)
protectedpure virtual

This method must implement features finding logic in order to make the wrappers detail::FeaturesFinder::operator()_ work.

Parameters
imageSource image
featuresFound features
See also
detail::ImageFeatures

§ isThreadSafe()

bool cv::detail::FeaturesFinder::isThreadSafe ( ) const
protected

uses dynamic_cast to determine thread-safety

Returns
True, if it's possible to use the same finder instance in parallel, false otherwise

§ operator()() [1/4]

void cv::detail::FeaturesFinder::operator() ( InputArray  image,
ImageFeatures features 
)

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

§ operator()() [2/4]

void cv::detail::FeaturesFinder::operator() ( InputArray  image,
ImageFeatures features,
const std::vector< cv::Rect > &  rois 
)

Finds features in the given image.

Parameters
imageSource image
featuresFound features
roisRegions of interest
See also
detail::ImageFeatures, Rect_

§ operator()() [3/4]

void cv::detail::FeaturesFinder::operator() ( InputArrayOfArrays  images,
std::vector< ImageFeatures > &  features,
const std::vector< std::vector< cv::Rect > > &  rois 
)

Finds features in the given images in parallel.

Parameters
imagesSource images
featuresFound features for each image
roisRegions of interest for each image
See also
detail::ImageFeatures, Rect_

§ operator()() [4/4]

void cv::detail::FeaturesFinder::operator() ( InputArrayOfArrays  images,
std::vector< ImageFeatures > &  features 
)

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