Inheritance Hierarchy

Namespace: Emgu.CV.Features2D
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)

Syntax

public abstract class Feature2D : SharedPtrObject, 
	IAlgorithm

Public MustInherit Class Feature2D
	Inherits SharedPtrObject
	Implements IAlgorithm

public ref class Feature2D abstract : public SharedPtrObject, 
	IAlgorithm

[<AbstractClassAttribute>]
type Feature2D =  
    class
        inherit SharedPtrObject
        interface IAlgorithm
    end

The Feature2D type exposes the following members.

Constructors

	Name	Description
	Feature2D	Initializes a new instance of the Feature2D class

Properties

	Name	Description
	DescriptorSize	Get the number of elements in the descriptor.
	Feature2DPtr	Get the pointer to the Feature2D object
	Ptr	Pointer to the unmanaged object (Inherited from UnmanagedObject.)
	SharedPtr	Pointer to the shared pointer to the unmanaged object (Inherited from SharedPtrObject.)

Methods

	Name	Description
	Compute	Compute the descriptors on the image from the given keypoint locations.
	Detect	Detect the keypoints from the image
	DetectAndCompute	Detect keypoints in an image and compute the descriptors on the image from the keypoint locations.
	DetectRaw	Detect the features in the image
	Dispose	The dispose function that implements IDisposable interface (Inherited from DisposableObject.)
	DisposeObject	Reset the pointers (Overrides DisposableObjectDisposeObject.)
	Equals	(Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	ReleaseManagedResources	Release the managed resources. This function will be called during the disposal of the current object. override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object (Inherited from DisposableObject.)
	ToString	(Inherited from Object.)

Fields

	Name	Description
	_algorithm	The pointer to the Algorithm object.
	_feature2D	The pointer to the Feature2D object
	_ptr	A pointer to the unmanaged object (Inherited from UnmanagedObject.)
	_sharedPtr	A pointer to the shared pointer to the unmanaged object (Inherited from SharedPtrObject.)

Extension Methods

	Name	Description
	Clear	Clear the algorithm (Defined by AlgorithmExtensions.)
	GetDefaultName	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. (Defined by AlgorithmExtensions.)
	IsEmpty	Returns true if the Algorithm is empty. e.g. in the very beginning or after unsuccessful read. (Defined by AlgorithmExtensions.)
	Load	Loads algorithm from the file (Defined by AlgorithmExtensions.)
	LoadFromString	Loads algorithm from a String (Defined by AlgorithmExtensions.)
	Read	Reads algorithm parameters from a file storage. (Defined by AlgorithmExtensions.)
	Save	Save the algorithm to file (Defined by AlgorithmExtensions.)
	SaveToString	Save the algorithm to a string (Defined by AlgorithmExtensions.)
	Write(FileStorage)	Overloaded. Stores algorithm parameters in a file storage (Defined by AlgorithmExtensions.)
	Write(FileStorage, String)	Overloaded. Stores algorithm parameters in a file storage (Defined by AlgorithmExtensions.)
