Find movement distance between two frames -- python

Question

I have a short video of a moving object. for some reason I need to estimate the object's movement distance between two specific frames. It is not necessary to be exact. Does anyone know how I can do this in python and opencv or any image processing library? Thanks

I don't know in opencv, there is for sure something similar but you can easily do it with scikit-image module. I do it on a regular basis to align frames.

See this example here:

EDIT: I found something very similar in opencv here
