Properties

	Name	Description
	AllocatedMemory	Gets or sets a memory address allocated by AllocMemory. (Inherited from DisposableObject.)
	AllocatedMemorySize	Gets or sets the byte length of the allocated memory (Inherited from DisposableObject.)
	CvPtr	Native pointer of OpenCV structure (Inherited from DisposableCvObject.)
	Empty	Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read (Inherited from Algorithm.)
	IsDisposed	Gets a value indicating whether this instance has been disposed. (Inherited from DisposableObject.)
	IsEnabledDispose	Gets or sets a value indicating whether you permit disposing this instance. (Inherited from DisposableObject.)

Methods

	Name	Description
	AllocGCHandle	Pins the object to be allocated by cvSetData. (Inherited from DisposableObject.)
	AllocMemory	Allocates the specified size of memory. (Inherited from DisposableObject.)
	CompareSegments	Draws two groups of lines in blue and red, counting the non overlapping (mismatching) pixels.
	Create	Creates a smart pointer to a LineSegmentDetector object and initializes it.
	Detect(InputArray, OutputArray, OutputArray, OutputArray, OutputArray)	Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.
	Detect(InputArray, Vec4f, Double, Double, Double)	Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.
	Dispose	Releases the resources (Inherited from DisposableObject.)
	DisposeManaged	Releases managed resources (Overrides DisposableObjectDisposeManaged.)
	DisposeUnmanaged	releases unmanaged resources (Inherited from DisposableCvObject.)
	DrawSegments	Draws the line segments on a given image.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	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. (Inherited from Algorithm.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyMemoryPressure	Notifies the allocated size of memory. (Inherited from DisposableObject.)
	Read	Reads algorithm parameters from a file storage (Inherited from Algorithm.)
	Save	Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage fs). (Inherited from Algorithm.)
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Stores algorithm parameters in a file storage (Inherited from Algorithm.)

Fields

	Name	Description
	dataHandle	Gets or sets a handle which allocates using cvSetData. (Inherited from DisposableObject.)
	ptr	Data pointer (Inherited from DisposableCvObject.)
