Detailed Description

Object tracker using Intersection-Over-Union (IOU)

"High-Speed Tracking-by-Detection Without Using Image Information" http://elvera.nue.tu-berlin.de/files/1517Bochinski2017.pdf

This tracker essentially performs temporal clustering of bounding boxes without using visual information, hence it is very fast but low accuracy.
