  • Export of Tracks to CVAT for Video and a custom CSV format (#24)

Changed

  • When creating tracks, if confs or classes are not provided, they are now given a default value, instead of being None. (#24)

[0.1.8] - 2022-10-05

Changed

  • Improve ID metrics to use less memory (#23)

[0.1.7] - 2022-10-02

Fixed

  • Fix typing for compatibility with Python 3.8 (#22)

[0.1.6] - 2022-09-29

Changed

  • Performance improvement for HOTA metrics using sparse matrices (#19)

[0.1.3] - 2022-08-21

Changed

  • MOT Metrics are now computed using the MOTMetrics class, which enables efficient sharing of pre-computed IoU distances across metrics (#17)
  • Increase minimum Python version to 3.9 (#16)
  • Switch packaging system to Poetry (#16)

[0.1.2] - 2022-08-14

Added

  • More integration tests (though for some reason, there are discrepancies with official results at times) (#12)
  • Filtering method for tracks (filter_by_class, filter_by_conf) (#12)
  • General method for reading CSV file (from_csv), reading MOT gt files (from_mot_gt) (#12)

Changed

  • Version large files for integration tests with git-lfs (#12)
  • All Track class methods for reading CSV files become just a wrapper around from_csv (#12)

[0.1.1] - 2021-08-14

Added

  • HOTA metrics can now be computed, using the original matching algorithm from the paper (gives similar results, but does not correspond to TrackEval's implementation)

[0.1.0] - 2021-08-07

Added

  • Tracks class, which represents the tracking data (detections), and provides loading functions to read from common MOT data formats
  • compute_mot_metrics function, which can calculate MOT metrics (for now CLEARMOT and ID metrics, HOTA coming soon, ALTA in the pipeline)
  • API documentation hosted on readthedocs
  • Pypi package
