Plotting 3d (x,y,z) or 2d (x,y) points in processed images

Hi All,
I have had a video of cells moving in blood vessels. I have obtained a series of binary images of the blood vessels structure in Fiji. Now I would like to plot few points (x,y,z) into this blood vessels by using some commands. How do I do it?

Any suggestions/hints is very much appreciated.
