There're two stages in selecting a valid trajectory.
First, a tracked bbox is picked only if it is matched with new observations (hit) in consecutive frames (hitStreak > minHitStreak
). (This is the method used in SORT algorithm)
Second, the picked bbox can be used to
If a trajectory hasn't been updated by any picked tracked bbox for a while, it will expire and I used these metrics to determine whether it is a valid falling object trajectory:
bboxes.count() > minNumOfBBoxes
),bboxes.last().Y - bboxes.first().Y > minVerticalSpan
)An expired trajectory can be output only if it satisfies both metrics.
Hello, I am very interested in your work. I want know that did you do some filtering operations after tracking? (For example, the noise tracklet caused by the shaking of the tree.)
