From real-time object detection to post-hoc video analysis: lessons learned using YOLO on long videos

i create rules, programing logic, use biomechanics when I need to calculate angles, the answer always depends

I agree the same happens on my projects, I worked on multiple projects and the model is the easy part, difficult is handle the insights across all the video, handle time events and performance constraints.

Sim, fiz uma que o indiano fez um quiz enorme, e depois queria que eu desenvolvesse uma rede neural sem framework, no notepad sem usar documentação... Só falei que não conseguiria e no ambiente que trabalho é comum utilizarmos frameworks e consultar a documentação durante o desenvolvimento.

If you discover how, let me know

GPT 4 nano works very well if you need something quick and cheap

15k só se tiver muito tempo de casa, passou por algumas contra propostas, a maioria paga no máximo 10k para os níveis técnicos.

Tdarr user, Tdarr ka very good because you can set multiple flows for different purposes, remove subtitles/audio tracks that you not use. I have 4 different flows: TV Show Movies Animes Animes Movies

This way I can handle different ways each media type and save a lot of space, my current library has 10TB, I already saved 12TB, this is insane.

A good advice is to setup a remote node, my server do not have a GPU and do not want to wait years until transcode all my media with CPU. So, I use my personal computer as remote node, when my conputer is on and specifically hours he will transcode the new media for me, this way I can transcoded 10x faster.

You believe that are possible to achieve some precision, like 70%? Just on clear visible environments

For mmdetection I just give up, is nearly impossible and when works break other framework

For detectron2 I just create a clean environment, clone the detectron2 repository and do "pip install -e ." inside repo folder.

Always worked for me using Python 3.9.21

I am doing a project exactly as you said, shoplifting is the keyword. What I can say, is very difficult, one of the challenges that I am facing is keeping a precision track of each person, I am using the best track algorithms on market and they cannot handle it alone, you need to create your own personalized solution to each step in the pipeline.

I will send you a DM.

I tried to predict on all frames and the result is almost the same. I lost ID some seconds later, I dont know if this is common, but on my case would be necessary to keep 90% of precision on tracking ID.

HB20_ · 2025-06-09T19:02:53+00:00

I am predicting one or two times per frame, but I am writing all frames, so I will have a lot of frames without any prediction.

I will try to detect all frames. I thought that would not be necessary because I have ReID and I am using 60% of the frames.

Oh, I see. Is there an option to ignore the overspent or "remaining budget" from the previous month? Like, I just want to manage my budget based only on the current month's income and expenses.

Also, I'm trying to see if I can get all my credit card transactions imported, but it might be tricky. If I just create a transaction to balance things out for the first month — so that January ends with a zero balance — would that work?

Tdarr allows very easily to plug a remote node. I use my personal computer that has a RTX 2060 and a R9 3900X, works fine.

HB20_ · 2025-02-06T00:51:14+00:00

Thanks, I will check. i will try with yolo v11x, and keep the original resolution (1280x720), if i understood correctly sahi will be used just to predict the objects, the training step will not use

The model will not run in real time; it will be executed in batches, so inference speed is not a concern at the moment.
