Member Function Documentation

collectGarbage()

virtual void cv::detail::FeaturesMatcher::collectGarbage ( )

inlinevirtual

Frees unused memory allocated before if there is any.

Reimplemented in cv::detail::BestOf2NearestMatcher.

isThreadSafe()

bool cv::detail::FeaturesMatcher::isThreadSafe ( ) const

inline

Returns

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

match()

virtual void cv::detail::FeaturesMatcher::match ( const ImageFeatures &  features1, const ImageFeatures &  features2, MatchesInfo &  matches_info  )

protectedpure virtual

This method must implement matching logic in order to make the wrappers detail::FeaturesMatcher::operator()_ work.

Parameters

features1	first image features
features2	second image features
matches_info	found matches

Implemented in cv::detail::AffineBestOf2NearestMatcher, and cv::detail::BestOf2NearestMatcher.

operator()() [1/2]

void cv::detail::FeaturesMatcher::operator() ( const ImageFeatures &  features1, const ImageFeatures &  features2, MatchesInfo &  matches_info  )

inline

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

Parameters

features1	First image features
features2	Second image features
matches_info	Found matches

References CV_OUT, CV_WRAP_AS, and cv::gapi::mask().

Here is the call graph for this function:

operator()() [2/2]

void cv::detail::FeaturesMatcher::operator()	(	const std::vector< ImageFeatures > &	features,
		std::vector< MatchesInfo > &	pairwise_matches,
		const cv::UMat &	mask = cv::UMat()
	)

Performs images matching.

Parameters

features	Features of the source images
pairwise_matches	Found pairwise matches
mask	Mask indicating which image pairs must be matched

The function is parallelized with the TBB library.
