Tracker uses only bounding boxes, no visual information.
Bounding boxes are associated frame-to-frame maximizing the IOU metric.
Re-identification phase projects discovered tracks to past/future tracks within a time window of 50 frames and quantifies the track matching score.
Fragmented tracks with high matching score are linked together, missing bounding boxes interpolated.
The proposed tracker is extremely fast compared to visual-based methods, and more accurate than (similar-to-our-work method) IOU17 thanks to the re-identification phase,
The proposed tracker is used to discover inter-person relationships in videos.
