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
