Integrate Integration of tracker through the official tutorial:
handle = vot.VOT("mask", multiobject=True) objects = handle.objects()

 the shape size of the mask obtained by the  handle.objects()  command  is not equal to the image shape, do we need to handle the offset by ourselves?  

By the way, during the evaluation tracking process:
handle.report([tracker.track(image) for tracker in trackers])

is the mask result reported by the tracker a binary image whose shape is the size of the original image? (e.g. a 2D ndarray of shape (720, 1280) with values 0 or 1)

Yes, mask is not padded from bottom-right with zeros unfortunately because the protocol does not know the size of the frame.

The reported mask can also be smaller or of same size as an image. The only important requirement is that positive (1) pixels should not exceed the region of a frame (although it may work, but it is not recommended).

cheers,
