Have you tried using object attributes/features to enable tracking instead of IOU-based tracking? I suspect this tracker falls apart when there are significant obstructions. Thoughts on a Recurrent YOLO or DeepSORT based tracker?

Yes. I am actually looking into this idea. I thought instead of recurrent yolo, Correlation Filter is much simpler.

I was referring the following papers:

2. https://zpascal.net/cvpr2018/He_A_Twofold_Siamese_CVPR_2018_...

I've found that IOU based tracking is surprisingly reliable (my dataset was primarily surveillance footage with a static camera) if you take measures to smooth the data and predict object motion using a kalman filter.

Kalman filter is also one good way to reliably keep track of objects under significant obstruction.
