Filter tracks by value

[MerihEkin]

Would it be possible to have an option to filter tracks (area, time) before running the optimization or drop some tracks from the list

Absolutely! How do you see this working? Do you want to filter the tracks in Python via your own script?

I am using a library for cell detection that includes some noise. For example, I've noticed that the trajectories associated with noise are usually shorter in duration or cover a smaller area. If I could filter out some trajectories—specifically with respect to track length or the convex hull area covered—between the tracking and optimization steps, I believe it would improve the results.

Alternatively, I can easily compute these parameters for each track, so a function to either drop trajectories by specific indices or retain those with specific indices would also be effective.

For instance:

tracker.track(step_size=100)
tracker.filter_tracks_by_index(list_of_track_indices_to_keep/drop)
tracker.optimize()

Thank you for considering this feature and for your efforts in maintaining such a useful library.
