com.google.android.gms.vision.MultiProcessor.Factory<T> |
Factory for creating new tracker instances. As new items are detected, each distinct item (as indicated by an item ID generated by the detector) will have a new instance of the tracker created for that item. A tracker will receive all notifications for that item for consecutive frames, until the item has been determined to be no longer present.
When onDone()
is called on a tracker instance, no future notifications will
be sent to that instance. Associated resources, if any, should be freed upon receiving that
call.
