Duplicate track-ids in ground truth training set

[victorjoos]

Hello,

When trying to train a tracker on your dataset, we noticed that some frames contain duplicate track ids, however, the bounding box is not the same, for example : (video 33)

Should we split this track id into two separate ids, or remove the second identity ?

After checking, we found that for duplicate track IDs, the later occurrence should be modified. Specifically, it should be updated to a value larger than the largest ID in the gt.txt file.
