Get associated measurement history for trackerGNN?

Hi,

I am using trackerGNN to form tracks on simulated measurements. At each time instant, the tracker() function returns a objectTrack. Is there a way to get the measurement that was associated to update the track (i.e., the measurement index that was used to update the track position and form the objectTrack)?

Thanks

Yes.

You can use

[confirmedTracks, ~, ~, info] = tracker(detections, time);

Then, in info, you can look for the field Assignments and find which track ID (first column) was assigned to which detection index (column 2).

Exactly what I was looking for! Thanks!
