C# Class OpenCvSharp.FlannBasedMatcher

Brute-force descriptor matcher. For each descriptor in the first set, this matcher finds the closest descriptor in the second set by trying each one.

Public Methods

Method	Description
Add ( IEnumerable descriptors ) : void	Add descriptors to train descriptor collection.
Clear ( ) : void	Clear train descriptors collection.
FlannBasedMatcher ( OpenCvSharp.Flann.IndexParams indexParams = null, OpenCvSharp.Flann.SearchParams searchParams = null ) : System
IsMaskSupported ( ) : bool	Return true if the matcher supports mask in match methods.
Train ( ) : void	Train matcher (e.g. train flann index). In all methods to match the method train() is run every time before matching. Some descriptor matchers (e.g. BruteForceMatcher) have empty implementation of this method, other matchers really train their inner structures (e.g. FlannBasedMatcher trains flann::Index). So nonempty implementation of train() should check the class object state and do traing/retraining only if the state requires that (e.g. FlannBasedMatcher trains flann::Index if it has not trained yet or if new descriptors have been added to the train collection).

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Releases the resources

Private Methods

Method	Description
FlannBasedMatcher ( IntPtr rawPtr ) : System	Creates instance by raw pointer T*
FlannBasedMatcher ( Ptr detectorPtr ) : System	Creates instance by cv::Ptr<T>
FromPtr ( IntPtr ptr ) : FlannBasedMatcher	Creates instance from cv::Ptr<T> . ptr is disposed when the wrapper disposes.

Method Details

Add() public method

Add descriptors to train descriptor collection.

public Add ( IEnumerable descriptors ) : void
descriptors	IEnumerable	Descriptors to add. Each descriptors[i] is a descriptors set from one image.
return	void

Clear() public method

Clear train descriptors collection.

public Clear ( ) : void
return	void

Dispose() protected method

Releases the resources

protected Dispose ( bool disposing ) : void
disposing	bool	/// If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. /// If false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed. ///
return	void

FlannBasedMatcher() public method

public FlannBasedMatcher ( OpenCvSharp.Flann.IndexParams indexParams = null, OpenCvSharp.Flann.SearchParams searchParams = null ) : System
indexParams	OpenCvSharp.Flann.IndexParams
searchParams	OpenCvSharp.Flann.SearchParams
return	System

IsMaskSupported() public method

Return true if the matcher supports mask in match methods.

public IsMaskSupported ( ) : bool
return	bool

Train() public method

Train matcher (e.g. train flann index). In all methods to match the method train() is run every time before matching. Some descriptor matchers (e.g. BruteForceMatcher) have empty implementation of this method, other matchers really train their inner structures (e.g. FlannBasedMatcher trains flann::Index). So nonempty implementation of train() should check the class object state and do traing/retraining only if the state requires that (e.g. FlannBasedMatcher trains flann::Index if it has not trained yet or if new descriptors have been added to the train collection).
