TargetManagement:
  enableBboxUnClipping: 1   # In case the bbox is likely to be clipped by image border, unclip bbox
  maxTargetsPerStream: 150  # Max number of targets to track per stream. Recommended to set >10. Note: this value should account for the targets being tracked in shadow mode as well. Max value depends on the GPU memory capacity

  # [Creation & Termination Policy]
  minIouDiff4NewTarget: 0.55   # If the IOU between the newly detected object and any of the existing targets is higher than this threshold, this newly detected object will be discarded.
  minTrackerConfidence: 0.2   # If the confidence of an object tracker is lower than this on the fly, then it will be tracked in shadow mode. Valid Range: [0.0, 1.0]
  probationAge: 5 # If the target's age exceeds this, the target will be considered to be valid.
  maxShadowTrackingAge: 30  # Max length of shadow tracking. If the shadowTrackingAge exceeds this limit, the tracker will be terminated.
  earlyTerminationAge: 1   # If the shadowTrackingAge reaches this threshold while in TENTATIVE period, the target will be terminated prematurely.
