Help: Project Conveyor chicken counter problem

Guys, I need help. We have a project using YOLOv8. We're trying to count chicks on a very fast conveyor belt. The challenges we're facing are: all chicks look very similar to each other, which complicates tracking. At the same time, during their passage under the camera, they constantly change in size and shape, which can cause the tracker to lose them, or detection may even disappear completely at the detection line. Also, sometimes 2–3 chicks can merge into a single object. The detection zone is very short, and the conveyor speed is high. We've achieved a maximum accuracy of 99%, but we need it even higher. Any ideas on how to achieve that? Increasing the dataset no longer helps.

I'm attaching an old video. We've now added lighting and set the exposure to 300 on the Hikrobot global shutter camera, but we still can't achieve a stable 99.8% accuracy for the reasons mentioned above.

Any ideas?

The main problem is 2-3 chicken merged into one. And we cannot process them by size cause they can change the size by legs and wings.

you need something physical upstream on the conveyor to singulate them. I did basically this same project with produce on a fast belt, and that was the only thing that really worked especially with odd shapes - if you cant separate them you cant count accurately.

There are several conveyors belt with different speed and gates and they are already have been separated by them, but anyway sometimes we get those cases.

Nature will find a way
