To implement Eulerian Video Magnification, begin by taking a video input and decomposing it into various spatial frequency bands using Laplacian pyramid decomposition. Next, analyze these pixel values over time and apply a temporal bandpass filter to isolate the frequency of interest. Once filtered, amplify the signal and add it back to the frequency frames. Finally, collapse the pyramid to reconstruct the video with enhanced features.
Please refer to the following links on Laplacian pyramid decomposition and bandpass filter:
