C# Class Emgu.CV.MotionHistory

The motion history class

For help on using this class, take a look at the Motion Detection example

Inheritance: DisposableObject

Public Methods

Method	Description
GetMotionComponents ( MemStorage storage ) : Seq	Get a sequence of motion component
MotionHistory ( double mhiDuration, double maxTimeDelta, double minTimeDelta ) : System	Create a motion history object
MotionHistory ( double mhiDuration, double maxTimeDelta, double minTimeDelta, System.DateTime startTime ) : System	Create a motion history object
MotionInfo ( System motionRectangle, double &angle, double &motionPixelCount ) : void	Given a rectagle area of the motion, output the angle of the motion and the number of pixels that are considered to be motion pixel
Update ( Byte>.Image image ) : void	Update the motion history with the specific image and current timestamp
Update ( Byte>.Image foregroundMask, System.DateTime timestamp ) : void	Update the motion history with the specific image and the specific timestamp

Method	Description
DisposeObject ( ) : void	Release unmanaged resources
ReleaseManagedResources ( ) : void	Release any images associated with this object

Release unmanaged resources

protected DisposeObject ( ) : void
return	void

Get a sequence of motion component

public GetMotionComponents ( MemStorage storage ) : Seq
storage	MemStorage	The storage used by the motion components
return	Seq

Create a motion history object

public MotionHistory ( double mhiDuration, double maxTimeDelta, double minTimeDelta ) : System
mhiDuration	double	In second, the duration of motion history you wants to keep
maxTimeDelta	double	In second. Any change happens between a time interval greater than this will not be considerred
minTimeDelta	double	In second. Any change happens between a time interval smaller than this will not be considerred.
return	System

Create a motion history object

public MotionHistory ( double mhiDuration, double maxTimeDelta, double minTimeDelta, System.DateTime startTime ) : System
mhiDuration	double	In second, the duration of motion history you wants to keep
maxTimeDelta	double	In second. Any change happens between a time interval larger than this will not be considerred
minTimeDelta	double	In second. Any change happens between a time interval smaller than this will not be considerred.
startTime	System.DateTime	The start time of the motion history
return	System

Given a rectagle area of the motion, output the angle of the motion and the number of pixels that are considered to be motion pixel

public MotionInfo ( System motionRectangle, double &angle, double &motionPixelCount ) : void
motionRectangle	System	The rectangle area of the motion
angle	double	The orientation of the motion
motionPixelCount	double	Number of motion pixels within silhoute ROI
return	void

Release any images associated with this object

protected ReleaseManagedResources ( ) : void
return	void

Update the motion history with the specific image and current timestamp

public Update ( Byte>.Image image ) : void
image	Byte>.Image	The image to be added to history
return	void

Update the motion history with the specific image and the specific timestamp

public Update ( Byte>.Image foregroundMask, System.DateTime timestamp ) : void
foregroundMask	Byte>.Image	The foreground of the image to be added to history
timestamp	System.DateTime	The time when the image is captured
return	void
