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
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.
