Object Tracking Using YOLOv4, Deep SORT, and TensorFlow

Learn how to Build an Object Tracker using YOLOv4, Deep SORT, and Tensorflow! Run the real-time object tracker on both webcam and video. This video will show you how to get the necessary code, setup required dependencies and run the tracker. It can be run using YOLOv4, YOLOv4-tiny or YOLOv3 object detection models.
#objecttracking #yolov4 #deepsort
YOLOv4 is a state of the art algorithm that uses deep convolutional neural networks to perform object detections. We can take the output of YOLOv4 feed these object detections into Deep SORT (Simple Online and Realtime Tracking with a Deep Association Metric) in order to create a highly accurate object tracker. Run Deep SORT with YOLOv4-tiny model and obtain even higher speed and FPS, perfect for mobile apps or edge devices such as Raspberry Pi or Jetson Nano.

In this video I cover:
1. Cloning the code and installing dependencies.
2. Converting YOLOv4 pre-trained model into TensorFlow model.
3. Running Object Tracker on video.
4. Filtering allowed classes to track.
5. Running Object Tracker with YOLOv4-tiny for high FPS.
6. Adding info flag to see detailed information on tracks.

Let me know what additions you would like added to the code and if you run into any issues. Cheers :)

[@alphalimit8]

Nice function, but the deep sort id sometimes changes within the same object, how to tackle this issue?

[@TheAIGuy]

Farhan Tandia in the track.py file you can make the ‘age’ variable bigger. This variable is how long an ID can be not seen before it forgets it.

[@TheCommentYouNeed]

First of all great tutorial :) Keep doing it. Is there any chance that you'll prepare/create a tutorial about gathering some statistics about tracked objects e.g. distance covered in total(let say in meters or km), current speed and so one. That could be really awesome to see content like this :) I hope you enjoy this idea. Best regards

[@ImranAli-zo8bi]

Great video. I have trained my custom yolov4 model according to your previous video. Can I run deepsort tracker on it? will it be enough to replace -- model yolov4 name to my --model yolo-custom_last.weights?. Thankyou

I would like to test my pre-trained weights for plate detection, how can I proceed?

[@rajathav3159]

To the guys for whom no bounding boxes appear in the video : create a new environment as he says in the beginning of the video and use this, rather than using one which you might have created earlier for some other purpose. This worked for me.

[@deepanshuvishwakarma316]

[@ragavendra6686]

Nice video! I have a question regarding DeepSORT. DeepSORT is trained to extract features only for the person class and not for other object classes. Did you make any changes to the model or do you use the Deepsort's feature extractor trained for people on all object classes? It would be great if you could make a video on multiple object classes tracking using deepsort.

[@gerhardheinzerling9880]

You did a very good job here. I downloaded the code, followed your instructions and it worked perfectly well on my Windows 10 machine (with gpu). There is just one strange thing. I followed a ball which is in plain sight all the time. No interruption no obstacles. Still it finds the same ball with three different tags on it (1, 2 and 4). It guess it looses the ball for some millisecs / one or more frames and finds it again in the next frame and starts a new counter. I will find out :-) Thank you very much for the excellent video!

[@cheesiangleow4782]

One question is about the DeepSORT tracker, i think it is trained with MARS dataset(only person), what i want to confirmed is that , does it track on any objects even though the DeepSORT model is only trained on person?

[@TheAIGuy]

CheeSiang Leow the deepSort model is indeed trained on the person class but from my experience it works extremely well on all classes. It will still track all classes, just might not be as accurate at reidentifying previously tracked objects!

Do I also have to create a (picture) .txt for these pictures, which are simply completely empty? Or do Yolo and Tensorflow take it that way, if there is no text file for an image, that there is nothing to be recognized there?

[@martindemeio]

Hello! Congrats for the model. It's really accurate and stable. I'd want to ask you if it is normal that the YOLO v4 algorithm takes 2 hours to process a 5 min video. I guess that something's wrong with my configuration. If it was designed to detect objects with the cam, it should be processing videos as fast as in real-time. I installed your "conda" configuration code using the tensorflow-gpu yml, though. Is it possible to speed it up? Thanks!

[@palaache]

@Martin De Meio Hey! Its usually because you arent processing the video on a GPU. Maybe your system doesn't have a GPU, or if it does, is not compatible.
