Joint Headlight Pairing and Vehicle Tracking by Weighted Set Packing in Nighttime Traffic Videos.

We propose a set packing (SP) framework for joint headlight pairing and vehicle tracking. Given headlight detections, traditional nighttime vehicle tracking methods usually first pair headlights and then track these pairs. However, the poor photometric condition often introduces tremendous noises in headlight detection and pairing, which leads to unrecoverable errors for vehicle tracking. To overc...
