Can I track objects by mapping their coordinates from a sequence of images?

I have a video of simple moving dots (that sometimes overlap) that is saved as a sequence of images. At each image I detect all the dots and save their coordinates: (snapshot 1 -> snapshot 2) I would like to infer the trajectory of each dot. The…
