Parameters
Type Name Description
MediaVisionSource source

The source of the media to recognize face for.
FaceTrackingModel trackingModel

The model will be used for tracking.
Boolean doLearn

The value indicating whether model learning while tracking.

Learning process improves tracking correctness, but can decrease tracking performance.
