C# Class Microsoft.Kinect.Toolkit.FaceTracking.FaceTracker

Main class that instantiates the face tracking engine and tracks the faces of a single person retrieving various metrics like animation units, 3D points and triangles on the face.

Méthodes publiques

Méthode	Description
Dispose ( ) : void	Disposes of the face tracking engine
FaceTracker ( KinectSensor sensor ) : System	Initializes a new instance of the FaceTracker class from a reference of the Kinect device. Reference to kinect sensor instance
ResetTracking ( ) : void	Resets IFTFaceTracker instance to the clean state (like it is in right after the call to Initialize() method)
Track ( ColorImageFormat colorImageFormat, byte colorImage, DepthImageFormat depthImageFormat, short depthImage ) : FaceTrackFrame	Starts face tracking from Kinect input data. Track() detects a face based on the passed parameters, then identifies characteristic points and begins tracking. The first call to this API is more expensive, but if the tracking succeeds then subsequent calls use the tracking information generated from first call and is faster, until a tracking failure happens.
Track ( ColorImageFormat colorImageFormat, byte colorImage, DepthImageFormat depthImageFormat, short depthImage, Rect regionOfInterest ) : FaceTrackFrame	Starts face tracking from Kinect input data. Track() detects a face based on the passed parameters, then identifies characteristic points and begins tracking. The first call to this API is more expensive, but if the tracking succeeds then subsequent calls use the tracking information generated from first call and is faster, until a tracking failure happens.

Private Methods

Méthode	Description
CheckPtrAndThrow ( ) : void
CreateResult ( int &hr ) : Microsoft.Kinect.Toolkit.FaceTracking.FaceTrackFrame	Creates a frame object instance. Can be used for caching of the face tracking frame. FaceTrackFrame should be disposed after use.
DepthToColorCallback ( uint depthFrameWidth, uint depthFrameHeight, uint colorFrameWidth, uint colorFrameHeight, float zoomFactor, Point viewOffset, int depthX, int depthY, ushort depthZ, int &colorX, int &colorY ) : int	Callback to help with mapping depth pixel to color pixel data. Uses Kinect sensor's MapDepthToColorImagePoint to do the conversion
GetHeadPointsFromSkeleton ( Skeleton skeletonOfInterest ) : Vector3DF[]	Helper API to retrieve head points structure from a given skeleton instance
Initialize ( CameraConfig newColorCameraConfig, CameraConfig newDepthCameraConfig, IntPtr colorImagePtr, IntPtr depthImagePtr, FaceTrackingRegisterDepthToColor newRegisterDepthToColorDelegate ) : void	Helper method that does the core instantiation & initialization of face tracking engine
Track ( ColorImageFormat colorImageFormat, byte colorImage, DepthImageFormat depthImageFormat, short depthImage, Skeleton skeletonOfInterest, Rect regionOfInterest ) : FaceTrackFrame	Starts face tracking from Kinect input data. Track() detects a face based on the passed parameters, then identifies characteristic points and begins tracking. The first call to this API is more expensive, but if the tracking succeeds then subsequent calls use the tracking information generated from first call and is faster, until a tracking failure happens.

Method Details

Dispose() public méthode

Disposes of the face tracking engine

public Dispose ( ) : void
Résultat	void

Dispose() protected méthode

Allows calling dispose explicitly or from the finalizer

protected Dispose ( bool disposing ) : void
disposing	bool	true to release both managed and unmanaged resources; false to release only unmanaged resources
Résultat	void

FaceTracker() public méthode

Initializes a new instance of the FaceTracker class from a reference of the Kinect device. Reference to kinect sensor instance

public FaceTracker ( KinectSensor sensor ) : System
sensor	KinectSensor
Résultat	System

ResetTracking() public méthode

Resets IFTFaceTracker instance to the clean state (like it is in right after the call to Initialize() method)

public ResetTracking ( ) : void
Résultat	void

Track() public méthode

Starts face tracking from Kinect input data. Track() detects a face based on the passed parameters, then identifies characteristic points and begins tracking. The first call to this API is more expensive, but if the tracking succeeds then subsequent calls use the tracking information generated from first call and is faster, until a tracking failure happens.
