I remember when I lead teams working with computer vision with object detection and tracking 4-5 years ago.

We didn’t want to mention AI and the training we did – we thought people would doubt the value.

Times are different now. 😉

Today most cloud providers also offer computer vision services.

Today you can build custom apps with no-code model training and low cost in a managed environment. Here is one I recommend and have tried successfully:

If you are more into Microsoft I can also recommend Azure AI Vision:
