        remain_inds = scores > self.args.track_thresh
        inds_low = scores > 0.1
        # inds_high = scores < self.args.track_thresh  # original
        inds_high = scores <= self.args.track_thresh  # proposal
        ...

If the score is exactly equal to self.args.track_thresh, the instance will be ignored even though it should be handled appropriately.

While this scenario is highly improbable, implementing the fix would improve the code slightly.

>>> a = np.array([.4, .499999999, .5, .500000001, .6], dtype=float)
>>> a > .5
array([False, False, False,  True,  True])
>>> a < .5
array([ True,  True, False, False, False])
