Object Detection and Tracking with Ultralytics YOLOv8 | Episode 7

Join us for our seventh video in this series as Nicolai Nielsen shows you how to do object tracking with Ultralytics YOLOv8. In this episode, you will learn how to use YOLOv8 to do object tracking live on a webcam and videos. Instead of just running object detection on individual frames, we can now track the objects over time between frames. We are going to see how to set it up and run it. We will also see some examples and results with object tracking.

Hi, does the tracking work if the object changes class as time goes? For example for the football field dataset if my labels were "player static" and "player running" would the tracking be able to follow the same player as it changes states? Thank you!

[JohnToridas]

what GPU do i need to have, to be able to run yolov models (at least the smallest one nano version) with minimal delay on streams, to achieve something close to realtime stream??

[audiogourmet]

HHi Ultralytics team, I would like to limit yolov8 to bound only the object with the highest confidence score on the screen at a time. How can I do that? And, I realized that If I made a query in code such as using 'IF' blocks, FPS is down drastically from 22 to 12. I wonder what is the reason for this?

[aydinrizqu]

Is the object tracking in yolov8 using deepsort so it can tracking the object ? And i wonder how can i use this tracker with yolov8 to make a camera that will folllow a person and make the object stay in the center

Great video! I'm curious, how does YOLOv8 handle occlusions and overlapping objects during tracking? Are there specific scenarios where it struggles?

[cjdhvcs]

did you do any labelling before abour the dancing girls? how does it work without labelling?

[fatmanursefer]

Hi, I collected data with video to use in my project. Can I use this video to train my model or do I need to train the model using only photos? If I can use it, how should I label the data in this video? I would appreciate it very much if you could help me on this issue.

[paularana]

hi just curious does ultralytics has speed estimation for moving objects?

[EdjeElectronics]

Are you guys doing a YOLO VISION conference again this year? I would love to attend and/or give a talk!

[partoflife]

Hello, how do I do it if I want to replace it with a model that I made myself, I'm confused about which one to change, help me☹️

Hello,

I have a question regarding the usage of the Ultralytics model.

Will the results be the same if I use model(source=1.avi, show=True, conf=0.4) compared to model.track(source=1.avi, show=True, conf=0.4)?

I would like to know if the results can differ regardless of the box size in the same frame. For example, in the 10th frame, is it possible for model() to detect a person while model.track() does not?

[thinhgak]

Hello Sir, how can I resize the "show=True" window?

[anandukc]

Helloo... If I want to track peoples in a region of interest or crossing a line can I use the same method.

Ultralytics requirement ['lapx>=0.5.2'] not found, attempting AutoUpdate...

I am getting this error while running the bytetracker. Is any installation need for bytetracker?

[karthikvjit]

Hello Ultralytics team, does the bytetrack algorithm runs on GPU? Or the box data is bought back onto CPU and then the tracking algorithm operates on CPU? Does track uses detection in between at regular intervals?

[jeanseanlee]

Great video as always! How do I fix the issue where the video that is shown is cropped when I run the code?

[sandaznadaz]

Can we change the id start from 1 for each class? For example, there is three object detected in image and the id by default is helmet: 1, person: 2, jacket: 3. Can we change it to helmet: 1, person: 1, jacket: 1 ? Thank you.

[Eison]

Hello, how can I create a timer for detected object?

[speedtv]

How to import Ultralytics on visual like you, do I need to download any libraries? Please help me

[elviskiilu]

Hello ultralytics team, Does this(tracking )only work for the yolov8 detection models or do segmentation yolov8 models work too with tracking
