halloween party project - real-time kissing classifier

I have a Halloween party in 2 weeks and trying to create a cool thing for it. We want to create a kissing booth that changes the \~vibe\~ when you kiss. Our vision is as follows:

\- live video stream of a blank scene / sometimes two people in front and at a relatively consistent distance

\- real-time binary classifier (is kissing / is not kissing)

\- classifier output would trigger lights / music to change

​

I'm looking for …
