I'm looking for a computer vision algorithm or method that can tell if the camera is moving in a video. Or maybe an alternate way of telling if the background is moving. I have a lot of videos and only want to keep the ones where the camera is stationary.
All videos feature a person talking directly to the camera (the person is mostly stationary throughout the video). I want to keep videos where the camera is stationary, but there are a lot of videos where the person is holding the camera and walking or the camera is moving around too much
I plan to run some algorithm one by one on a collection of videos to determine which video IDs have a moving camera in them.
