- vinnyglennon 9y agoI played around with OpenCV a lot in 2011. Just wondering what is the current playing field like in 2017.
- _dps 9y agoIf you have some more specifics (and maybe a few frames from example video) I could probably suggest a few simple approaches to try out. I do think a simple head-counter is probably not a bad approximation (assuming you don't need to know exactly how many people). Feel free to hit me up by email (in my profile).
