Extendable to counting number of people in frame ?

[thakurritesh19]

This is not a problem but an query if this can be extended to also count the number of people. I have implemented people counter using a different approach where a camera is mounted on a ceiling, but for an application I am developing I am more interested in extending this to do that too. So that it not only displays emotions but also count of people in the frame in real time.
