 1.  You can combine separate bounding boxes into tracks using the ``Person reidentification `` model.

-of the ``ReID`` type (in this case the ``Person reidentification`` model).
-You can set the following parameters:
-Model “threshold” is a maximum cosine distance between objects’ embeddings.
-“Maximum distance” defines a maximum radius that an object can diverge between adjacent frames.
