Member Function Documentation

◆ clear()

virtual void cv::Algorithm::clear ( )

inlinevirtualinherited

Clears the algorithm state.

Reimplemented in cv::FlannBasedMatcher, cv::DescriptorMatcher, and cv::cuda::DescriptorMatcher.

◆ detect()

virtual void cv::cuda::HoughCirclesDetector::detect	(	InputArray	src,
		OutputArray	circles,
		Stream &	stream = `Stream::Null()`
	)

pure virtual

Finds circles in a grayscale image using the Hough transform.

Parameters

src	8-bit, single-channel grayscale input image.
circles	Output vector of found circles. Each vector is encoded as a 3-element floating-point vector \((x, y, radius)\) .
stream	Stream for the asynchronous version.

See also: HoughCircles

◆ empty()

virtual bool cv::Algorithm::empty ( ) const

inlinevirtualinherited

Returns true if the Algorithm is empty (e.g.

in the very beginning or after unsuccessful read

Reimplemented in cv::DescriptorMatcher, cv::ml::StatModel, cv::Feature2D, cv::BaseCascadeClassifier, and cv::cuda::DescriptorMatcher.

◆ getCannyThreshold()

virtual int cv::cuda::HoughCirclesDetector::getCannyThreshold ( ) const

pure virtual

◆ getDefaultName()

virtual String cv::Algorithm::getDefaultName ( ) const

virtualinherited

Returns the algorithm string identifier.

This string is used as top level xml/yml node tag when the object is saved to a file or string.

Reimplemented in cv::AKAZE, cv::KAZE, cv::SimpleBlobDetector, cv::GFTTDetector, cv::AgastFeatureDetector, cv::FastFeatureDetector, cv::MSER, cv::ORB, cv::BRISK, and cv::Feature2D.

◆ getDp()

virtual float cv::cuda::HoughCirclesDetector::getDp ( ) const

pure virtual

◆ getMaxCircles()

virtual int cv::cuda::HoughCirclesDetector::getMaxCircles ( ) const

pure virtual

◆ getMaxRadius()

virtual int cv::cuda::HoughCirclesDetector::getMaxRadius ( ) const

pure virtual

◆ getMinDist()

virtual float cv::cuda::HoughCirclesDetector::getMinDist ( ) const

pure virtual

◆ getMinRadius()

virtual int cv::cuda::HoughCirclesDetector::getMinRadius ( ) const

pure virtual

◆ getVotesThreshold()

virtual int cv::cuda::HoughCirclesDetector::getVotesThreshold ( ) const

pure virtual

◆ load()

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::load	(	const String &	filename,
		const String &	objname = `String()`
	)

inlinestaticinherited

Loads algorithm from the file.

Parameters

filename	Name of the file to read.
objname	The optional name of the node to read (if empty, the first top-level node will be used)

This is static template method of Algorithm. It's usage is following (in the case of SVM):

Ptr<SVM> svm = Algorithm::load<SVM>("my_svm_model.xml");

In order to make this method work, the derived class must overwrite Algorithm::read(const FileNode& fn).

References CV_Assert, cv::FileNode::empty(), cv::FileStorage::getFirstTopLevelNode(), cv::FileStorage::isOpened(), and cv::FileStorage::READ.

Here is the call graph for this function:

◆ loadFromString()

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::loadFromString	(	const String &	strModel,
		const String &	objname = `String()`
	)

inlinestaticinherited

Loads algorithm from a String.

Parameters

strModel	The string variable containing the model you want to load.
objname	The optional name of the node to read (if empty, the first top-level node will be used)

This is static template method of Algorithm. It's usage is following (in the case of SVM):

Ptr<SVM> svm = Algorithm::loadFromString<SVM>(myStringModel);

References CV_WRAP, cv::FileNode::empty(), cv::FileStorage::getFirstTopLevelNode(), cv::FileStorage::MEMORY, and cv::FileStorage::READ.

Here is the call graph for this function:

◆ read() [1/2]

virtual void cv::Algorithm::read ( const FileNode & fn )

inlinevirtualinherited

Reads algorithm parameters from a file storage.

Reimplemented in cv::FlannBasedMatcher, cv::DescriptorMatcher, and cv::Feature2D.

◆ read() [2/2]

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::read ( const FileNode & fn )

inlinestaticinherited

Reads algorithm from the file node.

This is static template method of Algorithm. It's usage is following (in the case of SVM):

cv::FileStorage fsRead("example.xml", FileStorage::READ);

Ptr<SVM> svm = Algorithm::read<SVM>(fsRead.root());

In order to make this method work, the derived class must overwrite Algorithm::read(const FileNode& fn) and also have static create() method without parameters (or with all the optional parameters)

◆ save()

virtual void cv::Algorithm::save ( const String & filename ) const

virtualinherited

Saves the algorithm to a file.

In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

◆ setCannyThreshold()

virtual void cv::cuda::HoughCirclesDetector::setCannyThreshold ( int cannyThreshold )

pure virtual

◆ setDp()

virtual void cv::cuda::HoughCirclesDetector::setDp ( float dp )

pure virtual

◆ setMaxCircles()

virtual void cv::cuda::HoughCirclesDetector::setMaxCircles ( int maxCircles )

pure virtual

◆ setMinRadius()

virtual void cv::cuda::HoughCirclesDetector::setMinRadius ( int minRadius )

pure virtual

◆ setVotesThreshold()

pure virtual

◆ write() [1/2]

virtual void cv::Algorithm::write ( FileStorage & fs ) const

inlinevirtualinherited

Stores algorithm parameters in a file storage.

Reimplemented in cv::FlannBasedMatcher, cv::DescriptorMatcher, and cv::Feature2D.

References CV_WRAP.

Referenced by cv::Feature2D::write(), and cv::DescriptorMatcher::write().

Here is the caller graph for this function:

◆ write() [2/2]

void cv::Algorithm::write	(	const Ptr< FileStorage > &	fs,
		const String &	name = `String()`
	)		const

inherited

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

◆ writeFormat()

void cv::Algorithm::writeFormat ( FileStorage & fs ) const

protectedinherited
