Public Member Functions inherited from cv::Algorithm
	Algorithm ()
virtual	~Algorithm ()
virtual void	clear ()
	Clears the algorithm state.
virtual bool	empty () const
	Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read.
virtual String	getDefaultName () const
virtual void	read (const FileNode &fn)
	Reads algorithm parameters from a file storage.
virtual void	save (const String &filename) const
virtual void	write (FileStorage &fs) const
	Stores algorithm parameters in a file storage.
void	write (const Ptr< FileStorage > &fs, const String &name=String()) const
	simplified API for language bindingsThis is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Additional Inherited Members
Static Public Member Functions inherited from cv::Algorithm
template<typename _Tp >
static Ptr< _Tp >	load (const String &filename, const String &objname=String())
	Loads algorithm from the file.
template<typename _Tp >
static Ptr< _Tp >	loadFromString (const String &strModel, const String &objname=String())
	Loads algorithm from a String.
template<typename _Tp >
static Ptr< _Tp >	read (const FileNode &fn)

Detailed Description

Base class for dense optical flow algorithms

Member Function Documentation

virtual void cv::DenseOpticalFlow::calc ( InputArray  I0, InputArray  I1, InputOutputArray  flow  )

pure virtual

Python:
	flow	=	cv.DenseOpticalFlow.calc(	I0, I1, flow	)

Calculates an optical flow.

Parameters

I0	first 8-bit single-channel input image.
I1	second input image of the same size and the same type as prev.
flow	computed flow image that has the same size as prev and type CV_32FC2.

Implemented in cv::optflow::OpticalFlowPCAFlow.

virtual void cv::DenseOpticalFlow::collectGarbage ( )

pure virtual

Python:
	None	=	cv.DenseOpticalFlow.collectGarbage(		)

Releases all inner buffers.

Implemented in cv::optflow::OpticalFlowPCAFlow.
