[SOLVED] What is optical flow?

How to calculate optical flow of a video in python? How to calculate? How to separate frames of a video based on a threshold using optical flow?

Do you mean, opencv motion detection tracking?

Motion Estimation with Optical Flow

Basic motion detection and tracking with Python and OpenCV


I have a video where I want to find the direction of motion using optical flow, also I need the find a threshold, if the motion between two frames is more than this threshold than i will consider that motion, how to find that threshold?

Using Optical Flow to find direction of Motion
