yolov4-deepsort VS deep_sort

I have a video stream of a hiking trail and am trying to count the number of hikers per day. The camera never moves. At night you can also see headlamps :). Direction not as important as just a count of bodies passing through the image in a given time period. https://drive.google.com/file/d/1BwLzyHhrLafyAj5kYn-AfDVBtBBVQCsO/view. I've tried https://github.com/theAIGuysCode/yolov4-deepsort on the stream but it isn't picking up the people, maybe they're too low res for TF Object Detection?

I am trying to track objects in a sequence of images in order to count them. I was looking around for robust trackers since in my case, the camera moves with respect to the object. I found the DeepSORT tracker online and it seems like the solution to my problem. However, I am not sure of how I could train it for my own custom classes. I am currently looking at this repository and it seems to almost do the things I want, except for the counting part. Can anyone explain to me how I can train the DeepSORT tracker for my own classes? I am already training a YOLOv4 model on these custom classes. As a result, I have collected a labelled dataset for the training and validation purposes, and if I have to use images for the training.

I have tried to implement the YOLOv4 + DeepSort tracking from the AI Guys code presented here, just to get an idea of how to go about this, but from what I understand, I will need to train the DeepSORT tracker for detecting my own classes. I do not know how to do that.

You can try a detection and tracking paradigm for videos - it would be a lot more accurate than detection only without the need re-detect every frame which spends a lot of compute. E.g.: https://github.com/theAIGuysCode/yolov4-deepsort

And totally unecessary!! Next day, I discovered a GitHub project that simply used conda, as below.

Similari is a Rust/Python framework aimed at building sophisticated tracking systems. With Similari, you can develop highly efficient parallelized SORT, DeepSORT, and other sophisticated multiple-object tracking engines.

I'm doing a Python personal project where I'm trying to use YOLOv8 and DeepSORT to detect vehicles from a car's dash cam footage. I succeeded in using YOLOv8 to output the correct bounding boxes by processing each camera frame. However, I tried to add on DeepSORT code, but it made the detection accuracy significantly worse. I'm pretty sure I need to train my own "feature extractor" for DeepSORT to create a new .pb file. I got this information from the deep_sort GitHub link: https://github.com/nwojke/deep_sort. I tried to find resources to do this but they are pretty scarce. Has anyone had experience with this problem?

The feature model well that looks like it is at that domain you mentioned but why not instead of using this repo use the original authors repo

I was implementing the Kalman filter for bounding boxes during the last two days. As an inspiration source, I looked at the Python3 Kalman filter implementation that is used in the DeepSORT algorithm and uses NumPy and SciKit under the hood, so it's pretty efficient because all the operations are run inside FFI.

There's tons of work out there when it comes to object tracking such as DeepSort. We've worked to build simpler, more efficient solutions in-house though. Then past that, it's a matter of treating everything in the video as an object (including the whole frame), tracking it, and saving it in a no-SQL DB such that it's easy to query in this way.

Right now, the way we're thinking about it is to turn videos into something that works with the structure of a database like MongoDB. Everything in an image or a video is an object (even the frame itself is an object with a large bounding box), and each of these objects has some attributes and can be tracked over time with some form of object tracking. Given that the objects are tracked, they can each basically be returned as a time-series of each of the attributes associated with that object.

Deep Sort

I was wondering if I could use the same annotated data(in YOLO format) for the training of the tracker as well. I took a look at the original repo for DeepSORT, and it does mention the training using cosine metric learning, but I could not seem to understand how to replicate that for my own dataset(they show us how to do it for the MARS and Market1501 datasets).

DeepSORT is one of the best trackers https://github.com/nwojke/deep_sortIt requires an object detector tho, like YOLO https://pjreddie.com/darknet/yolo/
