TY for your great work on supervision library. I have modified your line counting algorithm. During counting people from indoor cctv camera, lines stay short to meet counting conditions. Firstly, I tried center dot instead of corners of bb, but it become unstable, especially when a person pass from door, because center of rectangle become unstable while object slowly disappear. Finally, I draw a square at center of object. It fits my case and generate stable countings.

Thank you for the amazing video! Is it possible to invoke yolo8 on every 4th frame (for example), instead of every single frame? And have some kind of other system follow the object in the other 3 frames (to save on resources).

Not to my knowledge. You skip the frame completely or not. All of those trackers depend on boxes being generated by the model. That being said you can try to pass detections to tracker every 4th frame. It all depends on input video but could still work.

For classification into car, bus, truck and motorcycle which one is used ByteTrack or Supervision? Additionally, is Bytetrack also used for counting along with tracking? Because supervision is used for annotations.

@danushkabandara Год назад

thanks for the video. I noticed that even with a clear view of all the vehicles, you still lose track of the truck and it gets a new id. Is there a way to limit the number of ids that the objects get so that this doesnt happen? for example you only have 4 possible labels during the video and the algorithm has to select the most likely label when tracking.

@SkalskiP Год назад

Is is possible to solve those issues. Or to at least make them less frequent. But potential solutions are usually strictly tied to use-case that you are trying to solve. In our case you can notice that those id changes are happening only when cars are still far away or when they are partially ocluded by this large metal object hanging over the left lane. Thats why I would propose to discard objects that are in top half of image and only take into account those that are in bottom half - closer.

@Roboflow 9 месяцев назад

ByteTrack is only responsible for tracking. The counting is done by line logic. Right now it is possible but you would need a separate line for every class. You don’t need to draw all of those line. But you would need LineZone object to perform the actual counting

it is possible to perform object tracking using YOLOv8 with a focus on two specific objects out of the 10 that the model detects. The code can be modified to track only those two predefined objects, providing you with the ability to monitor their movements and positions across frames. If you could provide additional details about the two objects you wish to track, I can assist you in adapting the code accordingly.

Suuperb... What if I want to detect and track the faulty chocolates in that video and mark the chocolate faulty until it leaves out the frame? Any thoughts on this?

@Roboflow Год назад

Do you have a model to detect those faults?

@snehitvaddi Год назад

@@Roboflow No, currently I have a model to detect potatoes on a conveyer belt. For detecting defects I'm thinking of using OpenCV to detect color deviations. My problem is since potatoes keep rotating on the conveyer belt, I want to track the defective potato even if it keeps rolling.

Hey Peter! Any thoughts on this? And also, Just now saw your video on Grounding DINO it looks interesting. What are your thoughts on using it to detect rotten/spoiled potatoes as explained in earlier comments.

@Roboflow Год назад

@@snehitvaddi sorry I missed your comment. If you have images of rotten potatoes you can try if DINO detect it. Sounds like something that should work. Color range is doable as well, just pretty hard to get right color ranges I think :/
