protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing	true to release both managed and unmanaged resources; otherwise false to release only unmanaged resources.

~FaceTrackingModel()

Finalizes an instance of the FaceTrackingModel class.

Declaration

protected ~FaceTrackingModel()

Prepare(MediaVisionSource, Quadrangle)

Initializes the tracking model by the location of the face to be tracked.

It is usually called once after the tracking model is created, and each time before tracking is started for the new sequence of sources, which is not the direct continuation of the sequence for which tracking has been performed before. But, it is allowed to call it between tracking sessions to allow Media Vision start to track more accurately.

Declaration

[Obsolete("Deprecated since API12. Will be removed in API15.")]
public void Prepare(MediaVisionSource source, Quadrangle region)

Parameters

Type	Name	Description
MediaVisionSource	source	The source where face location is specified. Usually it is the first frame of the video or the first image in the continuous image sequence planned to be used for tracking.
Quadrangle	region	The region determining position of the face to be tracked on the source. If null, then tracking model will try to find previously tracked face by itself.

Remarks

region needs to be the position of the face to be tracked when called first time for the tracking model. region is fitted to the valid region of source if region has invalid points.

Exceptions

Type	Condition
System.ArgumentNullException	source is null.
System.ObjectDisposedException	The FaceTrackingModel has already been disposed of. -or- source has already bean disposed of.

Save(string)

Saves the tracking model to the file.

Parameters

Type	Name	Description
string	path	Path to the file to save the model.

Exceptions

Type	Condition
System.ArgumentNullException	path is null.
System.UnauthorizedAccessException	No permission to write to the specified path.
System.ObjectDisposedException	The FaceTrackingModel has already been disposed of.
