Motion Amplification in Video Using Optical Flow

Abstract

This is a guide and demonstration of motion amplification in video using optical flow. The technique amplifies small motions that are invisible in the original video, rendering them visible to the naked eye. Restricting the amplification to specific frequency bands (e.g., those corresponding to peaks in the videos power spectral density) eliminates noise and isolates individual modes of vibration, precession, and so on.
