Member Function Documentation

collectGarbage()

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

inlinevirtual

Python:
	cv.detail.FeaturesMatcher.collectGarbage(		) ->	None

Frees unused memory allocated before if there is any.

Reimplemented in cv::detail::BestOf2NearestMatcher.

isThreadSafe()

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

inline

Python:
	cv.detail.FeaturesMatcher.isThreadSafe(		) ->	retval

Returns

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

match() [1/2]

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::BestOf2NearestMatcher, cv::detail::BestOf2NearestRangeMatcher, and cv::detail::AffineBestOf2NearestMatcher.

match() [2/2]

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

protectedvirtual

This method implements logic to match features between arbitrary number of features. By default this checks every pair of inputs in the input, but the behaviour can be changed by subclasses.

Parameters

features	vector of image features
pairwise_matches	found matches
mask	(optional) mask indicating which image pairs should be matched

Reimplemented in cv::detail::BestOf2NearestRangeMatcher.

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

operator()() [2/2]

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

inline

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.
