Basic questions about re-id and bounding boxes

[schelian]

This is fantastic work! I have some basic questions about re-id and bounding boxes for the community.

• If a bounding box is labeled 4 (e.g.) and then that box is transferred to another object, does that mean there was a re-id failure? Maybe the bounding box numbers are re-used somehow. I doubt that the numbers are re-used but I just wanted to check.
• Also, if there are many re-id failures, which parameters are best to modify? Is it conf_thres (confidence thresh for tracking)? Past that would one have to retrain the networks or use some other methods?

Thanks in advance & again great work!

It seems that it's a reid failure. conf_thres helps get better detection results. If you want to modify the reid results, you can go to multitracker.py and there are some parameters in the matching process, like reid distance thresh.

Would you tell me please, where is reid distance thresh in the multitracker.py?
