Member Function Documentation

§ collectGarbage()

virtual void cv::detail::FeaturesMatcher::collectGarbage ( )
inlinevirtual
Python:
None=cv.detail_FeaturesMatcher.collectGarbage()

Frees unused memory allocated before if there is any.

Reimplemented in cv::detail::BestOf2NearestMatcher.

§ isThreadSafe()

bool cv::detail::FeaturesMatcher::isThreadSafe ( ) const
inline
Python:
retval=cv.detail_FeaturesMatcher.isThreadSafe()
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
features1first image features
features2second image features
matches_infofound 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
features1First image features
features2Second image features
matches_infoFound 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() 
)

Performs images matching.

Parameters
featuresFeatures of the source images
pairwise_matchesFound pairwise matches
maskMask indicating which image pairs must be matched

The function is parallelized with the TBB library.
