Process connections
~~~~~~~~~~~~~~~~~~~

The following Input ports will need to be set
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code::

 # This process will consume the following input ports
 connect from <this-proc>.descriptor_set
          to   <upstream-proc>.descriptor_set
 connect from <this-proc>.feature_set
          to   <upstream-proc>.feature_set
 connect from <this-proc>.image

 connect from <this-proc>.timestamp
          to   <upstream-proc>.timestamp

The following Output ports will need to be set
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code::

 # This process will produce the following output ports
 connect from <this-proc>.feature_track_set
          to   <downstream-proc>.feature_track_set
