Multi-object trackers (SORT/Kalman vs scipy.spatial.distance)

Test of two different multi-object trackers:

• SORT/Kalman filter, with cross-line counting (with moving directions)
• Scipy spatial distance meter, with counting-by-tracking

Comparative testing done with YOLOv3/YOLOv2/TinyYOLO.

Cross-line counter (YOLOv3):
