How to calculate IDF1 metric for multi-camera multi-target(MCMT,MTMC) tracking?

[xifen523]

Description:
I am trying to evaluate the performance of a multi-camera multi-target tracking system and I would like to use the IDF1 metric. However, I am not sure how to calculate this metric for my specific setup. Can someone provide guidance on how to calculate IDF1 for multi-camera multi-target tracking?

Actual Results:
N/A

Reproducibility:
Always

Additional Information:
I am using Python and OpenCV for my tracking system. I have already implemented tracking and have ground truth data available. Any sample code or guidance would be greatly appreciated. Thank you!

There are CVMA and CVIDF1 metric defined in Complementary-View Multiple Human Tracking, but the author did not provide the calculation code for the indicators and did not explain the calculation process clearly.
paper DIVOTrack: A Novel Dataset and Baseline Method for Cross-View Multi-Object Tracking in DIVerse Open Scenes uses the same metric, but the metric evaluation code of DIVOTrack is not work and confusion.
