Recently I needed to detect people for a new pet project. I didn't do that for some time and decided to check out what is the best option for now.

So I read through some papers and run basic tests to measure accuracy and performance.

I had requirements — the objects are big enough but the surroundings could be very different and the detector should work as fast as possible. So I need a fast detector with a reasonable tradeoff. …
