The DeepStream SDK includes the gst-nvtracker plug-in. This plug-in allows the use of low-level tracker libraries for NvDCF, KLT, and IOU which track detected objects with unique IDs. The three reference implementations each have different hardware utilization profiles and performance. For a comparison and list of tradeoffs of these trackers, see Appendix E: Gst-nvtracker Tracker Library Comparison. The following figure shows the results of the object-detector model deployed in INT8 mode using three different tracker algorithms.
