run_burst_ow.py

""" run_burst_ow.py

The example commands given below expect the following folder structure:

- data
    - gt
        - burst
            - {val,test}
                - all_classes
                    - all_classes.json  (filename is irrelevant)
                - common_classes
                    - common_classes.json  (filename is irrelevant)
                - uncommon_classes.json
                    - uncommon_classes.json  (filename is irrelevant)
    - trackers
        - burst
            - open-world
                - {val,test}
                    - my_tracking_method
                        - data
                            - results.json  (filename is irrelevant)

Run example:

You'll need to run the eval script separately to get the OWTA metric for the three class splits. In the command below,
replace <SPLIT_NAME> with "common", "uncommon" and "all" to get the corresponding results.

run_burst_ow.py --USE_PARALLEL True --GT_FOLDER data/gt/burst/{val,test}/<SPLIT_NAME>_classes --TRACKERS_FOLDER data/trackers/burst/open-world/{val,test}
