demo sample about bytetrack

[nikky4D]

Thank you for the recommendation, and the addition in the README. I'm new to tracking and still finding it hard to use well. One more question for tracking: In the README sample, you call update on the current detections :

for image in images:
   dets = detector(image)
   online_targets = tracker.update(dets, info_imgs, img_size)

If you don't have a detection in the frame, do we skip tracking for that frame or call update with an empty list?

We have just added the tutorials of how to combine BYTE with other detectors. Hope that can help you :)
