How should I track multiple dots (1-2 mm) using opencv in real time?

I need to track dots (e.g. 10 red & 10 yellow ones) on black background in real-time. They will get names at the start(e.g. dot1,dot2, etc), so that they will be not confused in the process. Many trackers do not seem to be good at tracking little objects. So, which trackers and detection tools would you suggest? also, which is better for this kinds of job: python or c++?

ps I tried MOSSE and CSRT trackers, they don't seem to see small object well
