OpticalFlow workflow?

I’m new to OpenMV and currently testing optical flow on the H7.
I have a question: Does it work based on the opencv or it is a your own code of the optical flow, if so, where can I read the source code of how things work, cause I can’t find functions such as “find_displacement” anywhere on the Github page.
Thank you

Hi, you need to understand that code yourself. If you are new to C then you are diving into the deep end here.

(Also, I haven’t touched that method in years so I don’t know anymore. Don’t have time to look right now).
